LCM for 33 and 63
What's the Least Common Multiple (LCM) of 33 and 63?
(Six hundred ninety-three)
Finding LCM for 33 and 63 using GCF's of these numbers
The first method to find LCM for numbers 33 and 63 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 33 and 63 is 3, so
LCM = (33 × 63) ÷ 3
LCM = 2079 ÷ 3
LCM = 693
