What's the Least Common Multiple (LCM) of 13 and 65?

Answer: LCM of 13 and 65 is 65

(Sixty-five)

Finding LCM for 13 and 65 using GCF's of these numbers

The first method to find LCM for numbers 13 and 65 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 13 and 65 is 13, so

LCM = (13 × 65) ÷ 13

LCM = 845 ÷ 13

LCM = 65

Finding LCM for 13 and 65 by Listing Multiples

The second method to find LCM for numbers 13 and 65 is to list out the common multiples for both nubmers and pick the first which matching:

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

Multiples of 65: 65, 130, 195, 260, 325, 390, 455, [...], 65

So the LCM for 13 and 65 is 65

Finding LCM for 13 and 65 by Prime Factorization

Another method to find LCM for numbers 13 and 65 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

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

All Prime Factors of 65: 5, 13 (exponent form: 5¹, 13¹)

13¹ × 5¹ = 65
