LCM for 60 and 75
What's the Least Common Multiple (LCM) of 60 and 75?
(Three hundred)
Finding LCM for 60 and 75 using GCF's of these numbers
The first method to find LCM for numbers 60 and 75 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 60 and 75 is 15, so
LCM = (60 × 75) ÷ 15
LCM = 4500 ÷ 15
LCM = 300
Finding LCM for 60 and 75 by Listing Multiples
The second method to find LCM for numbers 60 and 75 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 60: 60, 120, 180, 240, 300, 360, 420
Multiples of 75: 75, 150, 225, 300, 375, 450
So the LCM for 60 and 75 is 300
Finding LCM for 60 and 75 by Prime Factorization
Another method to find LCM for numbers 60 and 75 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 60: 2, 2, 3, 5 (exponent form: 22, 31, 51)
All Prime Factors of 75: 3, 5, 5 (exponent form: 31, 52)
22 × 31 × 52 = 300
