WebOct 6, 2024 · A rational number in the form p/q, where p and q are integers, is said to be reduced to lowest terms if and only if GCD (p, q) = 1. That is, p/q is reduced to lowest terms if the greatest common divisor of both numerator and denominator is 1. As we saw in Example 7.2.3, the greatest common divisor of 12 and 18 is 6.
