LCM for 8 and 60
What's the Least Common Multiple (LCM) of 8 and 60?
(One hundred twenty)
Finding LCM for 8 and 60 using GCF's of these numbers
The first method to find LCM for numbers 8 and 60 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 8 and 60 is 4, so
LCM = (8 × 60) ÷ 4
LCM = 480 ÷ 4
LCM = 120
Finding LCM for 8 and 60 by Listing Multiples
The second method to find LCM for numbers 8 and 60 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128, 136
Multiples of 60: 60, 120, 180, 240
So the LCM for 8 and 60 is 120
Finding LCM for 8 and 60 by Prime Factorization
Another method to find LCM for numbers 8 and 60 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 8: 2, 2, 2 (exponent form: 23)
All Prime Factors of 60: 2, 2, 3, 5 (exponent form: 22, 31, 51)
23 × 31 × 51 = 120
