LCM for 191 and 211

The first method to find LCM for numbers 191 and 211 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 191 and 211 is 1, so

LCM = (191 × 211) ÷ 1

LCM = 40301 ÷ 1

LCM = 40301

The second method to find LCM for numbers 191 and 211 is to list out the common multiples for both nubmers and pick the first which matching:
