What's the Least Common Multiple (LCM) of 34 and 68?

Answer

LCM of 34 and 68 is
68

(Sixty-eight)

Finding LCM for 34 and 68 using GCF of these numbers

The first method to find LCM for numbers 34 and 68 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 34 and 68 is 34, so

LCM = (34 × 68) ÷ 34

LCM = 2,312 ÷ 34

LCM = 68

Finding LCM for 34 and 68 by Listing Multiples

The second method to find LCM for numbers 34 and 68 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 34: 34, 68, 102, 136

Multiples of 68: 68, 136, 204

So the LCM for 34 and 68 is 68

Finding LCM for 34 and 68 by Prime Factorization

Another method to find LCM for numbers 34 and 68 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 34: 2, 17 (exponent form: 21, 171)

All Prime Factors of 68: 2, 2, 17 (exponent form: 22, 171)

22 × 171 = 68
