LCM for 55 and 121
What's the Least Common Multiple (LCM) of 55 and 121?
(Six hundred five)
Finding LCM for 55 and 121 using GCF's of these numbers
The first method to find LCM for numbers 55 and 121 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 55 and 121 is 11, so
LCM = (55 × 121) ÷ 11
LCM = 6655 ÷ 11
LCM = 605
