This video explains how to find the prime factors of a number using the factor tree method, as well as how to write prime factors in index form. Practice questions and answers are at the end of the video.

This video explains how to find the lowest common multiple (LCM) of two or more numbers, using two methods: listing the multiples and using prime factorisation. Practice questions and answers are at the end of the video.

This video covers how to find the prime factors of a number by using a prime factor tree. This process is sometimes called prime factorisation. <b<br/>r/>

Suitable for courses across the world, including all KS3 and GCSE courses in the UK.

This video covers how to find the "Lowest Common Multiple" of a group of numbers. We cover 2 methods. The first is the easier method, which involves listing out the multiples of each number and picking the lowest multiple in...

This video covers how to find the "Highest Common Factor" of a group of numbers. We cover 2 methods. The first is the easier method, which involves listing out the factors of each number and picking the highest factor shared by...

We all know what numbers are 1, 2, 3, 4, 5, …. Including negative numbers -1, -2, -3, -4, -5, ... But did you know that mathematicians classify numbers into different types… into a number system. Let’s start at the top with real numbers....

Any natural number can be decomposed into a product of prime factors. Prime factorization is fundamental to many arithmetic operations involving fractions.

👉 Learn how to find the square root of a number. To find the square root of a number, we identify whether that number which we want to find its square root is a perfect square. This is done by identifying a number which when raised to...

SchoolOnline's Secondary Maths videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 13-17, they cover every key topic and sub topic covered in GCSE Maths in clear and easy to follow...

👉 Learn how to simplify the square root of an expression. The square root of an expression is an expression which will multiply itself twice to give the original expression. To simplify the square root of an expression, we...

This video is a lecture on the topic of the highest common factor (HCF). The presenter discusses what HCF is and how it is applied to a pair or set of numbers. They provide examples of finding the HCF of two numbers by listing their...

In this video lesson, students will learn how to write the square root of a negative number using the imaginary unit i. The lesson explains the difference between real and imaginary numbers and demonstrates how to simplify square roots...

Factors & Multiples | Number | Maths | FuseSchool In this video we are going to look at factors and multiples. Multiples are the timestables of a number. What we get by multiplying that number. The multiples of 3 are 3, 6, 9, 12, 15, and...

👉 Learn how to factor a number, variable, and monomial completely. To factor means to write our term as a product of its factors. Therefore we will learn how to break down a number, variable, and monomial into its factors.

This video is a lecture on the topic of the lowest common multiple (LCM) in mathematics. The video explains what the LCM is and how to calculate it for a pair of numbers. The process of prime factor decomposition is discussed as the...

👉 Learn how to factor a number, variable, and monomial completely. To factor means to write our term as a product of its factors. Therefore we will learn how to break down a number, variable, and monomial into its factors.

In this video tutorial I will show you how to factor out the GCF of an expression. We do this by first defining the GCF of the expression as the term with common elements with every term in the expression. We then divide every term by...

👉 Learn how to find the cube root of a number. To find the cube root of a number, we identify whether that number which we want to find its cube root is a perfect cube. This is done by identifying a number which when raised to the 3rd...

👉 Learn how to use the tools needed to graph a Polynomial function in standard form. The tools we will use to help us graph are end behavior, finding the zeros by factoring synthetic division as well as identify the multiplicity of each...

👉 Learn how to find the 3rd root of an expression. To find the 3rd root of an expression, if the exponent of the expression is a multiple of 3, then the 3rd root of the expression is the base of the expression with an exponent that is...

👉 Learn how to factor polynomials by GCF. A polynomial is an expression of the form ax^n + bx^(n-1) + . . . + k, where a, b, and k are constants and the exponents are positive integers. To factor an algebraic expression means to break it...
