LCM for 51 and 85
What's the Least Common Multiple (LCM) of 51 and 85?
(Two hundred fifty-five)
Finding LCM for 51 and 85 using GCF's of these numbers
The first method to find LCM for numbers 51 and 85 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 51 and 85 is 17, so
LCM = (51 × 85) ÷ 17
LCM = 4335 ÷ 17
LCM = 255
Finding LCM for 51 and 85 by Listing Multiples
