What is the formula for LCM ( 21, 27 )?
The formula of LCM is LCM (a,b) = (a × b) / GCF (a,b). We need to calculate greatest common factor 21 and 27, than apply into the LCM equation. GCF (21,27) = 3 LCM (21,27) = (21 × 27) / 3
Which is the least common multiple in this calculator?
Calculator Use The Least Common Multiple (LCM) is also referred to as the Lowest Common Multiple (LCM) and Least Common Divisor (LCD). For two integers a and b, denoted LCM (a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b. For example, LCM (2,3) = 6 and LCM (6,10) = 30.
