LCM for 318 and 416

The first method to find LCM for numbers 318 and 416 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 318 and 416 is 2, so

LCM = (318 × 416) ÷ 2

LCM = 132,288 ÷ 2

LCM = 66,144

The second method to find LCM for numbers 318 and 416 is to list out the common multiples for both numbers and pick the first one that matches:
