LCM for 5 and 54
What's the Least Common Multiple (LCM) of 5 and 54?
(Two hundred seventy)
Finding LCM for 5 and 54 using GCF's of these numbers
The first method to find LCM for numbers 5 and 54 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 5 and 54 is 1, so
LCM = (5 × 54) ÷ 1
LCM = 270 ÷ 1
LCM = 270
Finding LCM for 5 and 54 by Listing Multiples
The second method to find LCM for numbers 5 and 54 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140, 145, 150, 155, 160, 165, 170, 175, 180, 185, 190, 195, 200, 205, 210, 215, 220, 225, 230, 235, 240, 245, 250, 255, 260, 265, 270, 275, 280
Multiples of 54: 54, 108, 162, 216, 270, 324, 378
So the LCM for 5 and 54 is 270
