Are the two numbers 0 and 0 coprime (relatively prime, prime to each other)? Check if their greatest common factor, gcf, is equal to 1

Are the numbers 0 and 0 coprime (prime to each other, relatively prime)?

The numbers are not relatively prime... if:

If there is at least one number other than 1 that evenly divides the two numbers (without a remainder).

Or, in other words, if their greatest (highest) common factor (divisor), gcf (hcf, gcd), is not equal to 1.


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

Zero is divisible by any number other than itself (the remainder is zero when dividing it by those numbers).


gcf (hcf, gcd) (0; n) = n, where n is a natural number.

gcf (hcf, gcd) (0; 0) = 0 ≠ 1


Are the numbers 0 and 0 coprime (prime to each other, relatively prime)? No.

Are the two numbers coprime (relatively prime)?

Two natural numbers are coprime (relatively prime, prime to each other) - if there is no number that is evenly dividing both numbers (= without a remainder), that is, if their greatest (highest) common factor (divisor), gcf, or hcf, or gcd is 1.

Two natural numbers are not relatively prime - if there is at least one number that evenly divides the two numbers, that is, if their greatest common factor, gcf, is not 1.
