LCM for 100 and 255
What's the Least Common Multiple (LCM) of 100 and 255?
Answer
(Five thousand, one hundred)
Finding LCM for 100 and 255 using GCF of these numbers
The first method to find LCM for numbers 100 and 255 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 100 and 255 is 5, so
LCM = (100 × 255) ÷ 5
LCM = 25500 ÷ 5
LCM = 5100
Finding LCM for 100 and 255 by Listing Multiples
The second method to find LCM for numbers 100 and 255 is to list out the common multiples for both numbers and pick the first one that matches:
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, 2300, 2400, 2500, 2600, 2700, 2800, 2900, 3000, 3100, 3200, 3300, 3400, 3500, 3600, 3700, 3800, 3900, 4000, 4100, 4200, 4300, 4400, 4500, 4600, 4700, 4800, 4900, 5000, 5100, 5200, 5300
Multiples of 255: 255, 510, 765, 1020, 1275, 1530, 1785, 2040, 2295, 2550, 2805, 3060, 3315, 3570, 3825, 4080, 4335, 4590, 4845, 5100, 5355, 5610
So the LCM for 100 and 255 is 5100
Finding LCM for 100 and 255 by Prime Factorization
Another method to find LCM for numbers 100 and 255 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 100: 2, 2, 5, 5 (exponent form: 22, 52)
All Prime Factors of 255: 3, 5, 17 (exponent form: 31, 51, 171)
22 × 52 × 31 × 171 = 5100
