LCM for 2 and 13
What's the Least Common Multiple (LCM) of 2 and 13?
(Twenty-six)
Finding LCM for 2 and 13 using GCF's of these numbers
The first method to find LCM for numbers 2 and 13 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 2 and 13 is 1, so
LCM = (2 × 13) ÷ 1
LCM = 26 ÷ 1
LCM = 26
Finding LCM for 2 and 13 by Listing Multiples
The second method to find LCM for numbers 2 and 13 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30
Multiples of 13: 13, 26, 39, 52
So the LCM for 2 and 13 is 26
Finding LCM for 2 and 13 by Prime Factorization
Another method to find LCM for numbers 2 and 13 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 2: 2 (exponent form: 21)
All Prime Factors of 13: 13 (exponent form: 131)
21 × 131 = 26
