What's the Least Common Multiple (LCM) of 68 and 102?

Answer

LCM of 68 and 102 is
204

(Two hundred four)

Finding LCM for 68 and 102 using GCF of these numbers

The first method to find LCM for numbers 68 and 102 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 68 and 102 is 34, so

LCM = (68 × 102) ÷ 34

LCM = 6,936 ÷ 34

LCM = 204

Finding LCM for 68 and 102 by Listing Multiples

The second method to find LCM for numbers 68 and 102 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 68: 68, 136, 204, 272, 340

Multiples of 102: 102, 204, 306, 408

So the LCM for 68 and 102 is 204

Finding LCM for 68 and 102 by Prime Factorization

Another method to find LCM for numbers 68 and 102 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

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

All Prime Factors of 102: 2, 3, 17 (exponent form: 21, 31, 171)

22 × 171 × 31 = 204
