Answer 1

Answer:

75 and 57 are not coprime (relatively, mutually prime) if they have common prime factors, that is, if their greatest (highest) common factor (divisor), gcf, hcf, gcd, is not 1.

Answer 2

Answer:

Prime Factorization of a number - is finding the prime numbers that multiply together to make that number.

75 = 3 × 52;

75 is not a prime, is a composite number;

57 = 3 × 19;

57 is not a prime, is a composite number;

* Positive integers that are only dividing by themselves and 1 are called prime numbers. A prime number has only two factors: 1 and itself.

* A composite number is a positive integer that has at least one factor (divisor) other than 1 and itself.

Therefore, They are not co prime.
