What's the Least Common Multiple (LCM) of 55 and 65?

Answer

LCM of 55 and 65 is
715

(Seven hundred fifteen)

Finding LCM for 55 and 65 using GCF of these numbers

The first method to find LCM for numbers 55 and 65 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 55 and 65 is 5, so

LCM = (55 × 65) ÷ 5

LCM = 3,575 ÷ 5

LCM = 715

Finding LCM for 55 and 65 by Listing Multiples

The second method to find LCM for numbers 55 and 65 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 55: 55, 110, 165, 220, 275, 330, 385, 440, 495, 550, 605, 660, 715, 770, 825

Multiples of 65: 65, 130, 195, 260, 325, 390, 455, 520, 585, 650, 715, 780, 845

So the LCM for 55 and 65 is 715

Finding LCM for 55 and 65 by Prime Factorization

Another method to find LCM for numbers 55 and 65 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 55: 5, 11 (exponent form: 51, 111)

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

51 × 111 × 131 = 715
