LCM for 49 and 100
What's the Least Common Multiple (LCM) of 49 and 100?
Answer
(Four thousand nine hundred)
Finding LCM for 49 and 100 using GCF of these numbers
The first method to find LCM for numbers 49 and 100 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 49 and 100 is 1, so
LCM = (49 × 100) ÷ 1
LCM = 4,900 ÷ 1
LCM = 4,900
