LCM for 5 and 100
What's the Least Common Multiple (LCM) of 5 and 100?
(Hundred)
Finding LCM for 5 and 100 using GCF's of these numbers
The first method to find LCM for numbers 5 and 100 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 5 and 100 is 5, so
LCM = (5 × 100) ÷ 5
LCM = 500 ÷ 5
LCM = 100
Finding LCM for 5 and 100 by Listing Multiples
The second method to find LCM for numbers 5 and 100 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
Multiples of 100: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000, 2100, 2200, [...], 100
So the LCM for 5 and 100 is 100
Finding LCM for 5 and 100 by Prime Factorization
Another method to find LCM for numbers 5 and 100 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 100: 2, 2, 5, 5 (exponent form: 22, 52)
52 × 22 = 100
