LCM for 50 and 780
What's the Least Common Multiple (LCM) of 50 and 780?
(Three thousand, nine hundred)
Finding LCM for 50 and 780 using GCF's of these numbers
The first method to find LCM for numbers 50 and 780 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 50 and 780 is 10, so
LCM = (50 × 780) ÷ 10
LCM = 39000 ÷ 10
LCM = 3900
