What's the Least Common Multiple (LCM) of 17 and 68?

Answer: LCM of 17 and 68 is 68

(Sixty-eight)

Finding LCM for 17 and 68 using GCF's of these numbers

The first method to find LCM for numbers 17 and 68 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 17 and 68 is 17, so

LCM = (17 × 68) ÷ 17

LCM = 1156 ÷ 17

LCM = 68

Finding LCM for 17 and 68 by Listing Multiples

The second method to find LCM for numbers 17 and 68 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 17: 17, 34, 51, 68, 85, 102

Multiples of 68: 68, 136, 204, 272, 340, 408, [...], 68

So the LCM for 17 and 68 is 68
