What's the Least Common Multiple (LCM) of 34 and 38?

Answer

LCM of 34 and 38 is 646

(Six hundred forty-six)

Finding LCM for 34 and 38 using GCF of these numbers

The first method to find LCM for numbers 34 and 38 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 34 and 38 is 2, so

LCM = (34 × 38) ÷ 2

LCM = 1292 ÷ 2

LCM = 646

Finding LCM for 34 and 38 by Listing Multiples

The second method to find LCM for numbers 34 and 38 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 34: 34, 68, 102, 136, 170, 204, 238, 272, 306, 340, 374, 408, 442, 476, 510, 544, 578, 612, 646, 680, 714

Multiples of 38: 38, 76, 114, 152, 190, 228, 266, 304, 342, 380, 418, 456, 494, 532, 570, 608, 646, 684, 722

So the LCM for 34 and 38 is 646

Finding LCM for 34 and 38 by Prime Factorization

Another method to find LCM for numbers 34 and 38 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 38: 2, 19 (exponent form: 21, 191)

21 × 171 × 191 = 646
