Answer 2

Answer:

The number pair which is not co prime is 45,108.

Step-by-step explanation:

• Co prime numbers: The numbers which are prime with respect to each other are called co-prime numbers. The only common factor of co prime numbers is 1.

       Example- 15 and 16 are two numbers. By factorizing them we get, 15 = 1 × 3 × 5 and 16 = 1 × 2 × 2 × 2 × 2.

The only common factor is 1. So 15 and 16 are co prime numbers.

• Solutions:

1) 22 = 1 × 2 × 11 and 35 = 1 × 5 × 7. Only common factor is 1. So they are co prime numbers.

2)45 = 1 × 3 × 3× 5 and 108 = 1 × 2 × 2 × 3 × 3 × 3. Common factors are 1, 3,3. So they are not co prime numbers.

3)30 = 1 × 2 × 3 × 5 and 77 = 1 × 7 × 11 . Only common factor is 1. So they are co prime numbers.

4)55 = 1 × 5 × 11 and 68 = 1 × 2 × 2 × 17 . Only common factor is 1. So they are co prime numbers.
