Question

Are 20,29 co-primes?​

Answer 1

Answer:

No, 20 and 29 are not co prime

20 is not prime

Answer 2

20 = 2² × 5;

20 is not a prime, is a composite number;

;29 is a prime number, it cannot be broken down to other prime factors;

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.

>> Integer numbers prime factorization

Calculate greatest (highest) common factor (divisor):

Multiply all the common prime factors, by the lowest exponents (if any).

But the two numbers have no common prime factors.

gcf, hcf, gcd (20; 29) = 1;

coprime numbers (relatively prime)

ThereFore the Ans is NO.
