Answer:
28 1/2
Step-by-step explanation:
Integer numbers prime factorization:
57 = 3 × 19;
2 is a prime number, it cannot be broken down to other prime factors;
Multiply all the common prime factors, by the lowest exponents.
But the two numbers have no common prime factors.
gcf, hcf, gcd (57; 2) = 1;
coprime numbers (relatively prime);
