What's the Least Common Multiple (LCM) of 40 and 260?

Answer

LCM of 40 and 260 is 520

(Five hundred twenty)

Finding LCM for 40 and 260 using GCF of these numbers

The first method to find LCM for numbers 40 and 260 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 260 is 20, so

LCM = (40 × 260) ÷ 20

LCM = 10400 ÷ 20

LCM = 520

Finding LCM for 40 and 260 by Listing Multiples

The second method to find LCM for numbers 40 and 260 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 40: 40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440, 480, 520, 560, 600

Multiples of 260: 260, 520, 780, 1040

So the LCM for 40 and 260 is 520

Finding LCM for 40 and 260 by Prime Factorization

Another method to find LCM for numbers 40 and 260 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 40: 2, 2, 2, 5 (exponent form: 23, 51)

All Prime Factors of 260: 2, 2, 5, 13 (exponent form: 22, 51, 131)

23 × 51 × 131 = 520
