Answer: LCM of 39 and 55 is 2,145

(Two thousand, one hundred forty-five)

Finding LCM for 39 and 55 using GCF's of these numbers

The first method to find LCM for numbers 39 and 55 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 39 and 55 is 1, so

LCM = (39 × 55) ÷ 1

LCM = 2145 ÷ 1

LCM = 2145
