LCM for 11 and 66
What's the Least Common Multiple (LCM) of 11 and 66?
Answer
(Sixty-six)
Finding LCM for 11 and 66 using GCF of these numbers
The first method to find LCM for numbers 11 and 66 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 11 and 66 is 11, so
LCM = (11 × 66) ÷ 11
LCM = 726 ÷ 11
LCM = 66
Finding LCM for 11 and 66 by Listing Multiples
The second method to find LCM for numbers 11 and 66 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 11: 11, 22, 33, 44, 55, 66, 77, 88
Multiples of 66: 66, 132, 198
So the LCM for 11 and 66 is 66
Finding LCM for 11 and 66 by Prime Factorization
Another method to find LCM for numbers 11 and 66 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 66: 2, 3, 11 (exponent form: 21, 31, 111)
111 × 21 × 31 = 66
