What's the Least Common Multiple (LCM) of 6 and 13?

Answer

LCM of 6 and 13 is 78

(Seventy-eight)

Finding LCM for 6 and 13 using GCF of these numbers

The first method to find LCM for numbers 6 and 13 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 6 and 13 is 1, so

LCM = (6 × 13) ÷ 1

LCM = 78 ÷ 1

LCM = 78

Finding LCM for 6 and 13 by Listing Multiples

The second method to find LCM for numbers 6 and 13 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90

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

So the LCM for 6 and 13 is 78

Finding LCM for 6 and 13 by Prime Factorization

Another method to find LCM for numbers 6 and 13 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 6: 2, 3 (exponent form: 21, 31)

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

21 × 31 × 131 = 78
