LCM for 11 and 55
What's the Least Common Multiple (LCM) of 11 and 55?
(Fifty-five)
Finding LCM for 11 and 55 using GCF's of these numbers
The first method to find LCM for numbers 11 and 55 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 11 and 55 is 11, so
LCM = (11 × 55) ÷ 11
LCM = 605 ÷ 11
LCM = 55
Finding LCM for 11 and 55 by Listing Multiples
