LCM for 23 and 69
What's the Least Common Multiple (LCM) of 23 and 69?
(Sixty-nine)
Finding LCM for 23 and 69 using GCF's of these numbers
The first method to find LCM for numbers 23 and 69 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 23 and 69 is 23, so
LCM = (23 × 69) ÷ 23
LCM = 1587 ÷ 23
LCM = 69
Finding LCM for 23 and 69 by Listing Multiples
