Yes, they are relatively prime.
25 is relatively prime with 36. 25 is not relatively prime with 35.
As 77 = 7 x 11, any number that is not a multiple of 7 or 11 is relatively prime to 77, e.g. 25, 38, 123
It can be. 16 is relatively prime with 25.
Yes, they are relatively prime.
no
Relatively prime, yes.
No, 7 and 14 are not relatively prime. They share the factor 7.
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.
25 and 98 are not prime numbers
