LCM for 22 and 44

The first method to find LCM for numbers 22 and 44 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 22 and 44 is 22, so

LCM = (22 × 44) ÷ 22

LCM = 968 ÷ 22

LCM = 44

The second method to find LCM for numbers 22 and 44 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 22: 22, 44, 66, 88

Multiples of 44: 44, 88, 132, 176, 220, 264, 308, 352, 396, 440, 484, 528, 572, 616, 660, 704, 748, 792, 836, 880, 924, 968, 1012, 1056, 1100, 1144, 1188, 1232, 1276, 1320, 1364, 1408, 1452, 1496,
