LCM for 60 and 390
What's the Least Common Multiple (LCM) of 60 and 390?
Answer
(Seven hundred eighty)
Finding LCM for 60 and 390 using GCF of these numbers
The first method to find LCM for numbers 60 and 390 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 60 and 390 is 30, so
LCM = (60 × 390) ÷ 30
LCM = 23400 ÷ 30
LCM = 780
Finding LCM for 60 and 390 by Listing Multiples
The second method to find LCM for numbers 60 and 390 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, 420, 480, 540, 600, 660, 720, 780, 840, 900
Multiples of 390: 390, 780, 1170, 1560
So the LCM for 60 and 390 is 780
Finding LCM for 60 and 390 by Prime Factorization
