Yes.
As 13 is prime and is not a factor of 24, then they are relatively prime
13 and 24 are relatively prime.
No, they are not relatively prime.
Yes, 24 and 77 are relatively prime.
16 and 24 are not relatively prime. They have 2 as a common factor.
Yes, they are relatively prime.
Yes, they are relatively prime.
Yes, they are relatively prime.
No, 7 and 14 are not relatively prime. They share the factor 7.
Yes, 20 and 24 are relatively prime. The only factor they share is 1.
Two numbers which are "relatively prime" have no common prime factors. To illustrate, let's write several numbers in terms of their prime factors: 24 = 2 x 2 x 2 x 3 25 = 5 x 5 42 = 2 x 3 x 7 70 = 2 x 5 x 7 You can see that 24 and 25 are relatively prime, because they don't share any common prime factors. Likewise, 25 and 42 are relatively prime. 24 and 42, however, are NOT relatively prime because they share the common factors of 2 and 3. Likewise 25 and 70 are NOT relatively prime because they share the common factor 5. When a fraction is in its simplest form, the numerator and denominator are relatively prime.
