LCM for 11 and 121
What's the Least Common Multiple (LCM) of 11 and 121?
(One hundred twenty-one)
Finding LCM for 11 and 121 using GCF's of these numbers
The first method to find LCM for numbers 11 and 121 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 11 and 121 is 11, so
LCM = (11 × 121) ÷ 11
LCM = 1331 ÷ 11
LCM = 121
Finding LCM for 11 and 121 by Listing Multiples
The second method to find LCM for numbers 11 and 121 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121, 132, 143
Multiples of 121: 121, 242, 363, 484, 605, 726, 847, 968, 1089, 1210, 1331, 1452, 1573, [...], 121
So the LCM for 11 and 121 is 121
Finding LCM for 11 and 121 by Prime Factorization
Another method to find LCM for numbers 11 and 121 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 11: 11 (exponent form: 111)
All Prime Factors of 121: 11, 11 (exponent form: 112)
112 = 121
