# Factors of 30

## What is the factor?

Factors are integers you multiply together to get another integer. Also remember that the factors always include 1 and itself. NOTE: When finding the factors of a number, ask yourself “what numbers can be multiplied together to give me this number?.

## How to find the factors of 30?

THINK: What pairs of numbers can be multiplied together to give me 30?

Step 1: 1 x 30 = 30, so put these numbers in the factor list.

 1 … 30

Step 2: Take 2 and divide with 30. It gives 2 x 15 = 30.

 1 2 15 30
Step 3:Take 3 and divide with 30. It gives 3 x 10 = 30
 1 2 3 10 15 30

Step 4: Take 4 and divide with 30. The remainder will be 2. But factors always give 0 remainder. This means 4 is NOT a factor of 30.

Step 5: Take 5 and divide with 30. It gives 5 x 6 = 30.
 1 2 3 5 6 10 15 30
Step 6: Take 6 and divide with 30. It gives 6 x 5 = 30. but factors 6 and 5 are already in the list. So you dont need to repeat the number.
 1 2 3 5 6 10 15 30

Step 7: Take 7 and divide with 30. The remainder will be 2. But factors always give 0 remainder. This means 7 is NOT a factor of 30.

Step 8: Take 8 and divide with 30. The remainder will be 6. But factors always give 0 remainder. This means 8 is NOT a factor of 30.

Step 9: Take 9 and divide with 30. The remainder will be 3. But factors always give 0 remainder. This means 9 is NOT a factor of 30.

Step 10: Take 10 and divide with 30. It gives 10 x 3 = 30. but factors 10 and 3 are already in the list. So you dont need to repeat the number.

 1 2 3 5 6 10 15 30

So the factors of 30 are 1, 2, 3, 5, 6, 10, 15, 30.

TIPS: Try to keep tables (at least till 20) on your finger tips. Revise tables every day ## Is 30 a prime or composite number?
