LCM for 19 and 34
What's the Least Common Multiple (LCM) of 19 and 34?
(Six hundred forty-six)
Finding LCM for 19 and 34 using GCF's of these numbers
The first method to find LCM for numbers 19 and 34 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 19 and 34 is 1, so
LCM = (19 × 34) ÷ 1
LCM = 646 ÷ 1
LCM = 646
Finding LCM for 19 and 34 by Listing Multiples
The second method to find LCM for numbers 19 and 34 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 19: 19, 38, 57, 76, 95, 114, 133, 152, 171, 190, 209, 228, 247, 266, 285, 304, 323, 342, 361, 380, 399, 418, 437, 456, 475, 494, 513, 532, 551, 570, 589, 608, 627, 646, 665, 684
Multiples of 34: 34, 68, 102, 136, 170, 204, 238, 272, 306, 340, 374, 408, 442, 476, 510, 544, 578, 612, 646, 680, 714
So the LCM for 19 and 34 is 646
Finding LCM for 19 and 34 by Prime Factorization
Another method to find LCM for numbers 19 and 34 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 19: 19 (exponent form: 191)
All Prime Factors of 34: 2, 17 (exponent form: 21, 171)
191 × 21 × 171 = 646
