LCM for 2 and 22
What's the Least Common Multiple (LCM) of 2 and 22?
(Twenty-two)
Finding LCM for 2 and 22 using GCF's of these numbers
The first method to find LCM for numbers 2 and 22 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 2 and 22 is 2, so
LCM = (2 × 22) ÷ 2
LCM = 44 ÷ 2
LCM = 22
Finding LCM for 2 and 22 by Listing Multiples
The second method to find LCM for numbers 2 and 22 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26
Multiples of 22: 22, 44, 66, 88, 110, 132, 154, 176, 198, 220, 242, 264, 286, [...], 22
So the LCM for 2 and 22 is 22
Finding LCM for 2 and 22 by Prime Factorization
Another method to find LCM for numbers 2 and 22 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 2: 2 (exponent form: 21)
All Prime Factors of 22: 2, 11 (exponent form: 21, 111)
21 × 111 = 22
