What's the Least Common Multiple (LCM) of 13 and 8?

Answer

LCM of 13 and 8 is 104

(One hundred four)

Finding LCM for 13 and 8 using GCF of these numbers

The first method to find LCM for numbers 13 and 8 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 13 and 8 is 1, so

LCM = (13 × 8) ÷ 1

LCM = 104 ÷ 1

LCM = 104

Finding LCM for 13 and 8 by Listing Multiples

The second method to find LCM for numbers 13 and 8 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 13: 13, 26, 39, 52, 65, 78, 91, 104, 117, 130

Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120

So the LCM for 13 and 8 is 104

Finding LCM for 13 and 8 by Prime Factorization

Another method to find LCM for numbers 13 and 8 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 8: 2, 2, 2 (exponent form: 23)

131 × 23 = 104
