LCM for 5 and 13

What's the Least Common Multiple (LCM) of 5 and 13?

Answer: LCM of 5 and 13 is 65

(Sixty-five)

Finding LCM for 5 and 13 using GCF's of these numbers

The first method to find LCM for numbers 5 and 13 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 5 and 13 is 1, so

LCM = (5 × 13) ÷ 1

LCM = 65 ÷ 1

LCM = 65

Finding LCM for 5 and 13 by Listing Multiples

The second method to find LCM for numbers 5 and 13 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75

Multiples of 13: 13, 26, 39, 52, 65, 78, 91

So the LCM for 5 and 13 is 65

Finding LCM for 5 and 13 by Prime Factorization

Another method to find LCM for numbers 5 and 13 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 5: 5 (exponent form: 51)

All Prime Factors of 13: 13 (exponent form: 131)

51 × 131 = 65
