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.
The prime numbers between 45 and 65 are: 47, 53, 59 and 61
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.
Yes, 25 and 65 are relatively prime because their greatest common divisor (GCD) is 1. The prime factorization of 25 is (5^2), and for 65, it is (5 \times 13). Since they share a common factor of 5, they are not relatively prime.
Since the GCF of 45 and 56 is 1, they are relatively prime.
No, 65 and 70 are not relatively prime. Relatively prime numbers only have the number 1 as a common factor. 65 and 70 also have 5 as a common factor, so they are not relatively prime.
