LCM for 71 and 142

The first method to find LCM for numbers 71 and 142 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 71 and 142 is 71, so

LCM = (71 × 142) ÷ 71

LCM = 10082 ÷ 71

LCM = 142

The second method to find LCM for numbers 71 and 142 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 71: 71, 142, 213, 284

Multiples of 142: 142, 284, 426, 568, 710, 852, 994, 1136, 1278, 1420, 1562, 1704, 1846, 1988, 2130, 2272, 2414, 2556, 2698, 2840, 2982, 3124, 3266, 3408, 3550, 3692, 3834, 3976, 4118, 4260, 4402,
