What's the Least Common Multiple (LCM) of 55 and 88?

Answer

LCM of 55 and 88 is
440

(Four hundred forty)

Finding LCM for 55 and 88 using GCF of these numbers

The first method to find LCM for numbers 55 and 88 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 55 and 88 is 11, so

LCM = (55 × 88) ÷ 11

LCM = 4,840 ÷ 11

LCM = 440

Finding LCM for 55 and 88 by Listing Multiples

The second method to find LCM for numbers 55 and 88 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

Multiples of 88: 88, 176, 264, 352, 440, 528, 616

So the LCM for 55 and 88 is 440

Finding LCM for 55 and 88 by Prime Factorization

Another method to find LCM for numbers 55 and 88 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 88: 2, 2, 2, 11 (exponent form: 23, 111)

51 × 111 × 23 = 440
