LCM for 5 and 22
What's the Least Common Multiple (LCM) of 5 and 22?
(One hundred ten)
Finding LCM for 5 and 22 using GCF's of these numbers
The first method to find LCM for numbers 5 and 22 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 5 and 22 is 1, so
LCM = (5 × 22) ÷ 1
LCM = 110 ÷ 1
LCM = 110
Finding LCM for 5 and 22 by Listing Multiples
The second method to find LCM for numbers 5 and 22 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120
Multiples of 22: 22, 44, 66, 88, 110, 132, 154
So the LCM for 5 and 22 is 110
Finding LCM for 5 and 22 by Prime Factorization
Another method to find LCM for numbers 5 and 22 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 5: 5 (exponent form: 51)
All Prime Factors of 22: 2, 11 (exponent form: 21, 111)
51 × 21 × 111 = 110
