LCM for 10 and 11

The first method to find LCM for numbers 10 and 11 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 10 and 11 is 1, so

LCM = (10 × 11) ÷ 1

LCM = 110 ÷ 1

LCM = 110

The second method to find LCM for numbers 10 and 11 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130

Multiples of 11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121, 132
