In the lowest turms

3/215

Step-by-step explanation:

Integer numbers prime factorization

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

215 = 5 * 43

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

But the two numbers have no common prime factors

gcf, hcf, gcd (3; 215) = 1
