LCM for 100 and 100

The first method to find LCM for numbers 100 and 100 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 100 and 100 is 100, so

LCM = (100 × 100) ÷ 100

LCM = 10000 ÷ 100

LCM = 100

The second method to find LCM for numbers 100 and 100 is to list out the common multiples for both nubmers and pick the first which matching:
