What's the Least Common Multiple (LCM) of 47 and 57?

Answer

LCM of 47 and 57 is 2,679

(Two thousand, six hundred seventy-nine)

Finding LCM for 47 and 57 using GCF of these numbers

The first method to find LCM for numbers 47 and 57 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 47 and 57 is 1, so

LCM = (47 × 57) ÷ 1

LCM = 2679 ÷ 1

LCM = 2679

Finding LCM for 47 and 57 by Listing Multiples
