LCM for 78 and 156

The first method to find LCM for numbers 78 and 156 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 78 and 156 is 78, so

LCM = (78 × 156) ÷ 78

LCM = 12168 ÷ 78

LCM = 156

The second method to find LCM for numbers 78 and 156 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 78: 78, 156, 234, 312

Multiples of 156: 156, 312, 468, 624, 780, 936, 1092, 1248, 1404, 1560, 1716, 1872, 2028, 2184, 2340, 2496, 2652, 2808, 2964, 3120, 3276, 3432, 3588, 3744, 3900, 4056, 4212, 4368, 4524, 4680, 4836,
