LCM for 126 and 252

The first method to find LCM for numbers 126 and 252 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 126 and 252 is 126, so

LCM = (126 × 252) ÷ 126

LCM = 31752 ÷ 126

LCM = 252

The second method to find LCM for numbers 126 and 252 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 126: 126, 252, 378, 504

Multiples of 252: 252, 504, 756, 1008, 1260, 1512, 1764, 2016, 2268, 2520, 2772, 3024, 3276, 3528, 3780, 4032, 4284, 4536, 4788, 5040, 5292, 5544, 5796, 6048, 6300, 6552, 6804, 7056, 7308, 7560, 7812,
