LCM for 10 and 670

The first method to find LCM for numbers 10 and 670 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 10 and 670 is 10, so

LCM = (10 × 670) ÷ 10

LCM = 6700 ÷ 10

LCM = 670

The second method to find LCM for numbers 10 and 670 is to list out the common multiples for both nubmers and pick the first which matching:
