For example: 30 ÷ 6 = 5, and there is no

remainder. So we can say that 5 and 6 are the

factors of 30.

In the given example, we can further break up or

simplify the number 6 into its factors, that is, 2 and

3. In other words, when we multiply 5, 2 and 3, we

still get 30. Therefore, the factors of 30 are 5, 2,
and 3. Also, 5 × 2 = 10. So, 10 is also a factor of 30.

Similarly, 5 × 3 = 15. So, 15 is also a factor of 30.

Finally, the factors of 30 are 1, 2, 3, 5, 6, 10, 15 and

30

• The number 1 is the smallest factor of every

number.

• Every number will have a minimum of two

factors, 1 and the number itself.

• A number that has only two factors, 1 and

the number itself, is called a prime number.
