What's the Least Common Multiple (LCM) of 77 and 121?

Answer

LCM of 77 and 121 is
847

(Eight hundred forty-seven)

Finding LCM for 77 and 121 using GCF of these numbers

The first method to find LCM for numbers 77 and 121 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 77 and 121 is 11, so

LCM = (77 × 121) ÷ 11

LCM = 9,317 ÷ 11

LCM = 847

Finding LCM for 77 and 121 by Listing Multiples

The second method to find LCM for numbers 77 and 121 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 77: 77, 154, 231, 308, 385, 462, 539, 616, 693, 770, 847, 924, 1,001

Multiples of 121: 121, 242, 363, 484, 605, 726, 847, 968, 1,089

So the LCM for 77 and 121 is 847

Finding LCM for 77 and 121 by Prime Factorization

Another method to find LCM for numbers 77 and 121 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 77: 7, 11 (exponent form: 71, 111)

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

71 × 112 = 847
