LCM for 3 and 27
What's the Least Common Multiple (LCM) of 3 and 27?
(Twenty-seven)
Finding LCM for 3 and 27 using GCF's of these numbers
The first method to find LCM for numbers 3 and 27 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 3 and 27 is 3, so
LCM = (3 × 27) ÷ 3
LCM = 81 ÷ 3
LCM = 27
