What's the Least Common Multiple (LCM) of 47 and 51?

Answer

LCM of 47 and 51 is 2,397

(Two thousand, three hundred ninety-seven)

Finding LCM for 47 and 51 using GCF of these numbers

The first method to find LCM for numbers 47 and 51 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 47 and 51 is 1, so

LCM = (47 × 51) ÷ 1

LCM = 2397 ÷ 1

LCM = 2397

Finding LCM for 47 and 51 by Listing Multiples

The second method to find LCM for numbers 47 and 51 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 47: 47, 94, 141, 188, 235, 282, 329, 376, 423, 470, 517, 564, 611, 658, 705, 752, 799, 846, 893, 940, 987, 1034, 1081, 1128, 1175, 1222, 1269, 1316, 1363, 1410, 1457, 1504, 1551, 1598, 1645, 1692, 1739, 1786, 1833, 1880, 1927, 1974, 2021, 2068, 2115, 2162, 2209, 2256, 2303, 2350, 2397, 2444, 2491

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, 2346, 2397, 2448, 2499

So the LCM for 47 and 51 is 2397

Finding LCM for 47 and 51 by Prime Factorization

Another method to find LCM for numbers 47 and 51 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 47: 47 (exponent form: 471)

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

471 × 31 × 171 = 2397
