Question

Which of the following pair of numbers are co-prime numbers

Answer 1

Answer:

Pair of no.s are 88 and 157.

88 = 11^1 x 2^3 187=11^1 x 17^1 Since 11 is a common factor, they're not co-prime. 52 = 13^1 x 2^2 81 = 3^4 No common factor except 1, so they're co-prime. 35 = 7^1 x 5^1 39 = 3^1 x 13^1 No common factor except 1, so they're also co-prime.
