LCM for 13 and 75
What's the Least Common Multiple (LCM) of 13 and 75?
(Nine hundred seventy-five)
Finding LCM for 13 and 75 using GCF's of these numbers
The first method to find LCM for numbers 13 and 75 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 13 and 75 is 1, so
LCM = (13 × 75) ÷ 1
LCM = 975 ÷ 1
LCM = 975
