Question

check whether 40 and 375 co prime or not​

Answer 1

Answer:

no this is not coprime number

Answer 2

Step-by-step explanation:

40 and 375 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.

Approach 1. Integer numbers prime factorization. Approach 2. Euclid's algorithm.

Approach 1. Integer numbers prime factorization:

40 = 23 × 5;

375 = 3 × 53;

Calculate the greatest (highest) common factor (divisor), gcf, hcf, gcd:

Multiply all the common prime factors, by the lowest exponents.

gcf, hcf, gcd (40; 375) = 5;

The numbers have common prime factors.

Coprime numbers (relatively prime) (40; 375)? No.

gcf, hcf, gcd (40; 375) = 5.
