2. Classify the following into even and odd numbers:

3. Give all the factors of 72.

4. Is 63460 divisible by 18? Yes/No

5. Is 23 a factor of 166842? Yes/No

Factors

We have learnt that a factor of a number divides the number completely.

For example, 12 ÷ 1 = 12, 12 ÷ 2 = 6, 12 ÷ 3 = 4

Therefore, 1, 2, 3, 4, 6 and 12 are the factors of 12.
