LCM for 9 and 121
What's the Least Common Multiple (LCM) of 9 and 121?
Answer
(One thousand eighty-nine)
Finding LCM for 9 and 121 using GCF of these numbers
The first method to find LCM for numbers 9 and 121 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 9 and 121 is 1, so
LCM = (9 × 121) ÷ 1
LCM = 1,089 ÷ 1
LCM = 1,089
