Whole Number Division (F)

In this GCSE Maths quiz you will learn a few hints and tips that will make division a little bit easier! Use the divisibility tests when you are applying the ‘common sense’ check to your answers, and you can even use them to impress your friends!

• Only even numbers are divisible by 2.
• A number is divisible by 3 if the sum of the digits is in the three times table.
• If the last 2 digits of a number are in the four times table then it is divisible by 4.
• Only numbers ending in 0 or 5 are divisible by 5.
• For a number to be divisible by 6, it has to be divisible by 2 AND 3.
• The divisibility test for 7 is the hardest – take the last digit, multiply it by 2 and subtract from the other digits. If the answer is zero or in the seven times table then it is divisible by 7.
• Only the last three digits of a number need to be divisible by 8.
• A number is divisible by 9 if the sum of the digits is in the nine times table.
