Answer: LCM of 22 and 55 is 110

(One hundred ten)

Finding LCM for 22 and 55 using GCF's of these numbers

The first method to find LCM for numbers 22 and 55 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 22 and 55 is 11, so

LCM = (22 × 55) ÷ 11

LCM = 1210 ÷ 11

LCM = 110

Finding LCM for 22 and 55 by Listing Multiples

The second method to find LCM for numbers 22 and 55 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 22: 22, 44, 66, 88, 110, 132, 154

Multiples of 55: 55, 110, 165, 220

So the LCM for 22 and 55 is 110
