Help your students prepare for their Maths GCSE with this free prime factors worksheet of 30+ questions and answers
The prime factors of a number are factors of that number which are prime. Every composite number can be written as a product of its prime factors.
The factors of a number are values which divide exactly into the number. For example, the factors of 12 are 1, 2, 3, 4, 6 and 12.
Prime numbers are integers whose only factors are themselves and 1. Examples of prime numbers are 2, 3, 5, 7 and 11.
To find the prime factors of a number, we can draw a prime factor tree, breaking down the number into pairs of factors until we achieve all prime numbers. The prime factorisation of a number is often written using exponents, in index form, for example 72=2^(3)*3^(2).
The prime factors of two or more given numbers can be used to find the HCF and LCM of those numbers.
Looking forward, students can then progress to additional number worksheets, for example a multiplying and dividing decimals worksheet or an order of operations worksheet.
