LCM for 14 and 49
What's the Least Common Multiple (LCM) of 14 and 49?
(Ninety-eight)
Finding LCM for 14 and 49 using GCF's of these numbers
The first method to find LCM for numbers 14 and 49 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 14 and 49 is 7, so
LCM = (14 × 49) ÷ 7
LCM = 686 ÷ 7
LCM = 98
Finding LCM for 14 and 49 by Listing Multiples
