LCM for 5 and 25
What's the Least Common Multiple (LCM) of 5 and 25?
(Twenty-five)
Finding LCM for 5 and 25 using GCF's of these numbers
The first method to find LCM for numbers 5 and 25 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 5 and 25 is 5, so
LCM = (5 × 25) ÷ 5
LCM = 125 ÷ 5
LCM = 25
Finding LCM for 5 and 25 by Listing Multiples
The second method to find LCM for numbers 5 and 25 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
Multiples of 25: 25, 50, 75, 100, 125, 150, 175, [...], 25
So the LCM for 5 and 25 is 25
Finding LCM for 5 and 25 by Prime Factorization
Another method to find LCM for numbers 5 and 25 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 25: 5, 5 (exponent form: 52)
52 = 25
