Answer: LCM of 55 and 121 is 605

(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

Finding LCM for 55 and 121 by Listing Multiples
