No, 30 and 135 are not relatively prime.

No, 30 and 40 are not relatively prime. Their greatest common factor is 10.

No, 30 and 36 are not relatively prime. They share the factors 3 and 6.

No. Even numbers can't be relatively prime.

12 and 30 are not relatively prime because they have two common prime factors (2 and 3).

No!

No.

30 and 49 are relatively prime because the GCF (greatest common factor) is 1. The definition of a relatively prime number is two nonzero numbers that have a GCF of 1.

Yes.

138 is not prime. 138 = 2 * 3 * 23

The gcf is 15; so 30 and 135 are not relatively prime. 30 = 2 x 3 x 5 135 = 33 x 5 hcf = 3 x 5 = 15 If the gcf of two numbers is 1, then they are relatively prime 15 ≠ 1, thus 30 and 135 are not relatively prime.

30 and 63 are relatively prime numbers. The factors of 30 are 1, 2, 3, 5, and 30, and the factors of 63 are 1, 7, 9, and 63. Two or more numbers are relatively prime if 1 is their only common factor.
