What's the Least Common Multiple (LCM) of 55 and 66?

Answer: LCM of 55 and 66 is 330

(Three hundred thirty)

Finding LCM for 55 and 66 using GCF's of these numbers

The first method to find LCM for numbers 55 and 66 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 55 and 66 is 11, so

LCM = (55 × 66) ÷ 11

LCM = 3630 ÷ 11

LCM = 330

Finding LCM for 55 and 66 by Listing Multiples

The second method to find LCM for numbers 55 and 66 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 55: 55, 110, 165, 220, 275, 330, 385, 440

Multiples of 66: 66, 132, 198, 264, 330, 396, 462

So the LCM for 55 and 66 is 330

Finding LCM for 55 and 66 by Prime Factorization

Another method to find LCM for numbers 55 and 66 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 66: 2, 3, 11 (exponent form: 2¹, 3¹, 11¹)

5¹ × 11¹ × 2¹ × 3¹ = 330
