Web31 jan. 2024 · A notion of gcd and lcm for rationals arises naturally by extending the divisibility relation from integers to rationals, i.e. for rationals r, s, we define r divides s, if s / r is an integer, in symbols r s s / r ∈ Z [such divisibility relations induced by subrings are discussed further here ]. WebThe steps to calculate the GCD of (a, b) using the LCM method is: Step 1: Find the product of a and b. Step 2: Find the least common multiple (LCM) of a and b. Step 3: Divide the values obtained in Step 1 and Step 2. Step 4: The obtained value after division is the greatest common divisor of (a, b).
