LCM for 680 and 612
What's the Least Common Multiple (LCM) of 680 and 612?
Answer
(Six thousand, one hundred twenty)
Finding LCM for 680 and 612 using GCF of these numbers
The first method to find LCM for numbers 680 and 612 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 680 and 612 is 68, so
LCM = (680 × 612) ÷ 68
LCM = 416160 ÷ 68
LCM = 6120
