LCM for 60 and 80
What's the Least Common Multiple (LCM) of 60 and 80?
Answer
(Two hundred forty)
Finding LCM for 60 and 80 using GCF of these numbers
The first method to find LCM for numbers 60 and 80 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 60 and 80 is 20, so
LCM = (60 × 80) ÷ 20
LCM = 4800 ÷ 20
LCM = 240
Finding LCM for 60 and 80 by Listing Multiples
The second method to find LCM for numbers 60 and 80 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 60: 60, 120, 180, 240, 300, 360
Multiples of 80: 80, 160, 240, 320, 400
So the LCM for 60 and 80 is 240
Finding LCM for 60 and 80 by Prime Factorization
Another method to find LCM for numbers 60 and 80 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 80: 2, 2, 2, 2, 5 (exponent form: 24, 51)
24 × 31 × 51 = 240
