LCM for 11 and 12
What's the Least Common Multiple (LCM) of 11 and 12?
(One hundred thirty-two)
Finding LCM for 11 and 12 using GCF's of these numbers
The first method to find LCM for numbers 11 and 12 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 11 and 12 is 1, so
LCM = (11 × 12) ÷ 1
LCM = 132 ÷ 1
LCM = 132
Finding LCM for 11 and 12 by Listing Multiples
The second method to find LCM for numbers 11 and 12 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121, 132, 143, 154
Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156
So the LCM for 11 and 12 is 132
Finding LCM for 11 and 12 by Prime Factorization
Another method to find LCM for numbers 11 and 12 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 11: 11 (exponent form: 111)
All Prime Factors of 12: 2, 2, 3 (exponent form: 22, 31)
111 × 22 × 31 = 132
