LCM for 6 and 22
What's the Least Common Multiple (LCM) of 6 and 22?
(Sixty-six)
Finding LCM for 6 and 22 using GCF's of these numbers
The first method to find LCM for numbers 6 and 22 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 6 and 22 is 2, so
LCM = (6 × 22) ÷ 2
LCM = 132 ÷ 2
LCM = 66
Finding LCM for 6 and 22 by Listing Multiples
The second method to find LCM for numbers 6 and 22 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78
Multiples of 22: 22, 44, 66, 88, 110
So the LCM for 6 and 22 is 66
Finding LCM for 6 and 22 by Prime Factorization
Another method to find LCM for numbers 6 and 22 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 6: 2, 3 (exponent form: 21, 31)
All Prime Factors of 22: 2, 11 (exponent form: 21, 111)
21 × 31 × 111 = 66
