LCM for 5 and 245
What's the Least Common Multiple (LCM) of 5 and 245?
(Two hundred forty-five)
Finding LCM for 5 and 245 using GCF's of these numbers
The first method to find LCM for numbers 5 and 245 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 5 and 245 is 5, so
LCM = (5 × 245) ÷ 5
LCM = 1225 ÷ 5
LCM = 245
