5 and 8
No, coprime numbers have no common factors other than one; 15 and 24 both have the factor 3, so they are not coprime.
The GCF is 1.
Only 1: the two numbers are coprime.
18 factors to [2 3 3] 34 factors to [2 17] They have a common factor of 2, so they are not coprime.
To find the coprimes of 161, first determine its prime factors. The prime factorization of 161 is (7 \times 23). A number is coprime to 161 if it shares no common factors with 161 other than 1. Therefore, any integer that is not divisible by 7 or 23 is a coprime of 161.
No. If two numbers are coprime, they must have no common factors.
1, they are coprime.
9 (factors 1, 3, and 9) and 10 (factors 1, 2, 5, and 10) are coprime numbers. Numbers are coprime (also called relatively prime) if 1 is their only common factor.
51 and 40 are coprime so the ratio 51/40 cannot be simplified.
Numbers are co-prime if their GCF is 1.
No, coprime numbers have no common factors other than one; 15 and 24 both have the factor 3, so they are not coprime.
The numbers that go into both -13 and 40 are 1 and -1. This is because the factors of -13 are 1, -1, 13, and -13, while the factors of 40 are 1, -1, 2, -2, 4, -4, 5, -5, 8, -8, 10, -10, 20, and -20. The only common factors between -13 and 40 are 1 and -1.
Only 1: the two numbers are coprime.
The GCF is 1.
The numbers are coprime. Their only common factor is 1.
No. The two numbers have multiple common factors, the highest of which is 12.
8 and 15 share no common factors aside from 1. 8 and 15 are coprime.
