LCM for 43 and 51
What's the Least Common Multiple (LCM) of 43 and 51?
Answer
(Two thousand, one hundred ninety-three)
Finding LCM for 43 and 51 using GCF of these numbers
The first method to find LCM for numbers 43 and 51 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 43 and 51 is 1, so
LCM = (43 × 51) ÷ 1
LCM = 2193 ÷ 1
LCM = 2193
Finding LCM for 43 and 51 by Listing Multiples
The second method to find LCM for numbers 43 and 51 is to list out the common multiples for both numbers and pick the first one that matches:
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, 1032, 1075, 1118, 1161, 1204, 1247, 1290, 1333, 1376, 1419, 1462, 1505, 1548, 1591, 1634, 1677, 1720, 1763, 1806, 1849, 1892, 1935, 1978, 2021, 2064, 2107, 2150, 2193, 2236, 2279
Multiples of 51: 51, 102, 153, 204, 255, 306, 357, 408, 459, 510, 561, 612, 663, 714, 765, 816, 867, 918, 969, 1020, 1071, 1122, 1173, 1224, 1275, 1326, 1377, 1428, 1479, 1530, 1581, 1632, 1683, 1734, 1785, 1836, 1887, 1938, 1989, 2040, 2091, 2142, 2193, 2244, 2295
So the LCM for 43 and 51 is 2193
Finding LCM for 43 and 51 by Prime Factorization
Another method to find LCM for numbers 43 and 51 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 43: 43 (exponent form: 431)
All Prime Factors of 51: 3, 17 (exponent form: 31, 171)
431 × 31 × 171 = 2193
