Finding LCM for 63 and 72 using GCF's of these numbers
The first method to find LCM for numbers 63 and 72 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 63 and 72 is 9, so
LCM = (63 × 72) ÷ 9
LCM = 4536 ÷ 9
LCM = 504
Finding LCM for 63 and 72 by Listing Multiples
