Answer 2

Answer:

xample 1: 21 and 22

For 21 and 22:

The factors of 21 are 1, 3, 7, and 21.

The factors of 22 are 1, 2, 11, and 22.

Here 21 and 22 have only one common factor that is 1. Hence, their HCF is 1 and are co-prime.

Example 2: 21 and 27

For 21 and 27:

The factors of 21 are 1, 3, 7, and 21.

The factors of 27 are 1, 3, 9, and 27.

Here 21 and 27 have two common factors; they are 1 and 3. HCF is 3 and they are not co-prime.
