Check if two numbers are coprime
WebCoprime Numbers. All integer values can be expressed as the product of their prime factors. These are the prime numbers that, when multiplied, yield the original value. For example, the value 12 is the product of the prime numbers 2, 2 and 3. Two values are said to be coprime if they have no common prime factors. For example, the values nine (3 ... Webprintf ("Enter 2 positive numbers\n"); scanf ("%d%d", &n1, &n2); if( coprime (n1, n2) ) { printf ("%d and %d are co-prime numbers.\n", n1, n2); } else { printf ("%d and %d are not co-prime numbers.\n", n1, n2); } return 0; } Output 1: Enter 2 positive numbers 8 15 8 and 15 are co-prime numbers. Output 2: Enter 2 positive numbers 12 15
