no,31 and 62 coprimes are not coprimes . as ,62 is divisible by 31 .so,their GCD=2

Coprimes, or relative primes, are two or more numbers that share no common divisors. To determine whether numbers are relatively prime, find their greatest common denominaotr. If it's one, they're coprime.

First, find the prime factorization of the number. For instance, with 45: 45 = 3 * 3 * 5 = 32 * 51 Now, from this prime factorization, any numbers whose prime factorizations do not include these factors is coprime to the number you have.

-2 + (-5) = -2 -5 = -7

{2, 2, 5, 6, 7} {2, 2, 5, 6, 7} {2, 2, 5, 6, 7} {2, 2, 5, 6, 7}

Coprimes require two integers 50 and 1 are coprimes for example, but 50 and 6 are not because both are evenly divisible by 2. 1 number cannot be a co-prime.

Yes

Yes. Their only common factor is 1.

are co-prime

The GCF of any set of numbers containing two (or more) coprimes is 1. So YES, 1 can be a GCF.

1000000000 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 = 29 * 59

5√2*5√2=5*5*√2*√2=5*5*2=25*2=50

It is: 2/5 of 5 = 2

The answer is: 5 divided by 5/2 = 2
