Answer

LCM of 13 and 26 is 26

(Twenty-six)

Finding LCM for 13 and 26 using GCF of these numbers

The first method to find LCM for numbers 13 and 26 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 13 and 26 is 13, so

LCM = (13 × 26) ÷ 13

LCM = 338 ÷ 13

LCM = 26

Finding LCM for 13 and 26 by Listing Multiples

The second method to find LCM for numbers 13 and 26 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 13: 13, 26, 39, 52

Multiples of 26: 26, 52, 78

So the LCM for 13 and 26 is 26

Finding LCM for 13 and 26 by Prime Factorization

Another method to find LCM for numbers 13 and 26 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 26: 2, 13 (exponent form: 21, 131)

131 × 21 = 26
