LCM for 5 and 55
What's the Least Common Multiple (LCM) of 5 and 55?
(Fifty-five)
Finding LCM for 5 and 55 using GCF's of these numbers
The first method to find LCM for numbers 5 and 55 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 5 and 55 is 5, so
LCM = (5 × 55) ÷ 5
LCM = 275 ÷ 5
LCM = 55
Finding LCM for 5 and 55 by Listing Multiples
The second method to find LCM for numbers 5 and 55 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
Multiples of 55: 55, 110, 165, 220, 275, 330, 385, 440, 495, 550, 605, 660, 715, [...], 55
So the LCM for 5 and 55 is 55
Finding LCM for 5 and 55 by Prime Factorization
Another method to find LCM for numbers 5 and 55 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 55: 5, 11 (exponent form: 51, 111)
51 × 111 = 55
