What's the Least Common Multiple (LCM) of 34 and 43?

Answer

LCM of 34 and 43 is
1,462

(One thousand four hundred sixty-two)

Finding LCM for 34 and 43 using GCF of these numbers

The first method to find LCM for numbers 34 and 43 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 34 and 43 is 1, so

LCM = (34 × 43) ÷ 1

LCM = 1,462 ÷ 1

LCM = 1,462

Finding LCM for 34 and 43 by Listing Multiples

The second method to find LCM for numbers 34 and 43 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, 748, 782, 816, 850, 884, 918, 952, 986, 1,020, 1,054, 1,088, 1,122, 1,156, 1,190, 1,224, 1,258, 1,292, 1,326, 1,360, 1,394, 1,428, 1,462, 1,496, 1,530

Multiples of 43: 43, 86, 129, 172, 215, 258, 301, 344, 387, 430, 473, 516, 559, 602, 645, 688, 731, 774, 817, 860, 903, 946, 989, 1,032, 1,075, 1,118, 1,161, 1,204, 1,247, 1,290, 1,333, 1,376, 1,419, 1,462, 1,505, 1,548

So the LCM for 34 and 43 is 1,462

Finding LCM for 34 and 43 by Prime Factorization

Another method to find LCM for numbers 34 and 43 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 43: 43 (exponent form: 431)

21 × 171 × 431 = 1,462
