LCM for 11 and 13
What's the Least Common Multiple (LCM) of 11 and 13?
(One hundred forty-three)
Finding LCM for 11 and 13 using GCF's of these numbers
The first method to find LCM for numbers 11 and 13 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 11 and 13 is 1, so
LCM = (11 × 13) ÷ 1
LCM = 143 ÷ 1
LCM = 143
Finding LCM for 11 and 13 by Listing Multiples
The second method to find LCM for numbers 11 and 13 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, 165
Multiples of 13: 13, 26, 39, 52, 65, 78, 91, 104, 117, 130, 143, 156, 169
So the LCM for 11 and 13 is 143
Finding LCM for 11 and 13 by Prime Factorization
Another method to find LCM for numbers 11 and 13 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 13: 13 (exponent form: 131)
111 × 131 = 143
