Asked by admin @ in Math viewed by 347 People
Which of the following pair of numbers are co-prime numbers ?
(a) 88 and 187 (b) 52 and 81 (c) 35 and 39
Answered by admin @
88 = 11^1 x 2^3
187=11^1 x 17^1
Since 11 is a common factor, they're not coprime.
52 = 13^1 x 2^2
81 = 3^4
No common factor except 1, so they're coprime.
35 = 7^1 x 5^1
39 = 3^1 x 13^1
No common factor except 1, so they're also coprime.
