LCM for 40 and 370
What's the Least Common Multiple (LCM) of 40 and 370?
Answer
(One thousand, four hundred eighty)
Finding LCM for 40 and 370 using GCF of these numbers
The first method to find LCM for numbers 40 and 370 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 40 and 370 is 10, so
LCM = (40 × 370) ÷ 10
LCM = 14800 ÷ 10
LCM = 1480
Finding LCM for 40 and 370 by Listing Multiples
The second method to find LCM for numbers 40 and 370 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 40: 40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440, 480, 520, 560, 600, 640, 680, 720, 760, 800, 840, 880, 920, 960, 1000, 1040, 1080, 1120, 1160, 1200, 1240, 1280, 1320, 1360, 1400, 1440, 1480, 1520, 1560
Multiples of 370: 370, 740, 1110, 1480, 1850, 2220
So the LCM for 40 and 370 is 1480
