No. Two numbers are "relatively prime" if they contain no common factors, i.e. they have a greatest common factor (GCF) of 1.
45 = 3 x 3 x 5
65 = 5 x 13
Their GCF is the common factor 5.
No, 50 and 65 are not relatively prime.
No, they are not relatively prime.
Prime factorization of 45 is 3x3x5. Prime factorization of 65 is 5x13.
Yes, 45 and 64 are relatively prime because they do not share any prime factors.
No.
Yes, they are relatively prime.
39 and 45 are not relatively prime because they have 3 as a common factor. Relatively prime numbers have no common factor greater than 1.
Since the GCF of 45 and 56 is 1, they are relatively prime.
The prime numbers between 45 and 65 are: 47, 53, 59 and 61
yes
Yes.
No, they are not.
