Answer: LCM of 51 and 68 is 204

(Two hundred four)

Finding LCM for 51 and 68 using GCF's of these numbers

The first method to find LCM for numbers 51 and 68 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 51 and 68 is 17, so

LCM = (51 × 68) ÷ 17

LCM = 3468 ÷ 17

LCM = 204

Finding LCM for 51 and 68 by Listing Multiples

The second method to find LCM for numbers 51 and 68 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 51: 51, 102, 153, 204, 255, 306

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

So the LCM for 51 and 68 is 204

Finding LCM for 51 and 68 by Prime Factorization

Another method to find LCM for numbers 51 and 68 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 51: 3, 17 (exponent form: 31, 171)

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

31 × 171 × 22 = 204
