What's the Least Common Multiple (LCM) of 66 and 121?

Answer

LCM of 66 and 121 is
726

(Seven hundred twenty-six)

Finding LCM for 66 and 121 using GCF of these numbers

The first method to find LCM for numbers 66 and 121 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 66 and 121 is 11, so

LCM = (66 × 121) ÷ 11

LCM = 7,986 ÷ 11

LCM = 726

Finding LCM for 66 and 121 by Listing Multiples

The second method to find LCM for numbers 66 and 121 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 66: 66, 132, 198, 264, 330, 396, 462, 528, 594, 660, 726, 792, 858

Multiples of 121: 121, 242, 363, 484, 605, 726, 847, 968

So the LCM for 66 and 121 is 726

Finding LCM for 66 and 121 by Prime Factorization

Another method to find LCM for numbers 66 and 121 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 66: 2, 3, 11 (exponent form: 21, 31, 111)

All Prime Factors of 121: 11, 11 (exponent form: 112)

21 × 31 × 112 = 726
