LCM for 100 and 275
What's the Least Common Multiple (LCM) of 100 and 275?
Answer
(One thousand one hundred)
Finding LCM for 100 and 275 using GCF of these numbers
The first method to find LCM for numbers 100 and 275 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 100 and 275 is 25, so
LCM = (100 × 275) ÷ 25
LCM = 27,500 ÷ 25
LCM = 1,100
Finding LCM for 100 and 275 by Listing Multiples
The second method to find LCM for numbers 100 and 275 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, 1,000, 1,100, 1,200, 1,300
Multiples of 275: 275, 550, 825, 1,100, 1,375, 1,650
So the LCM for 100 and 275 is 1,100
Finding LCM for 100 and 275 by Prime Factorization
Another method to find LCM for numbers 100 and 275 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 275: 5, 5, 11 (exponent form: 52, 111)
22 × 52 × 111 = 1,100
