LCM for 4 and 13
What's the Least Common Multiple (LCM) of 4 and 13?
(Fifty-two)
Finding LCM for 4 and 13 using GCF's of these numbers
The first method to find LCM for numbers 4 and 13 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 4 and 13 is 1, so
LCM = (4 × 13) ÷ 1
LCM = 52 ÷ 1
LCM = 52
Finding LCM for 4 and 13 by Listing Multiples
The second method to find LCM for numbers 4 and 13 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60
Multiples of 13: 13, 26, 39, 52, 65, 78
So the LCM for 4 and 13 is 52
Finding LCM for 4 and 13 by Prime Factorization
Another method to find LCM for numbers 4 and 13 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 4: 2, 2 (exponent form: 22)
All Prime Factors of 13: 13 (exponent form: 131)
22 × 131 = 52
