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