LCM for 29 and 57
What's the Least Common Multiple (LCM) of 29 and 57?
Answer
(One thousand six hundred fifty-three)
Finding LCM for 29 and 57 using GCF of these numbers
The first method to find LCM for numbers 29 and 57 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 29 and 57 is 1, so
LCM = (29 × 57) ÷ 1
LCM = 1,653 ÷ 1
LCM = 1,653
Finding LCM for 29 and 57 by Listing Multiples
The second method to find LCM for numbers 29 and 57 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 29: 29, 58, 87, 116, 145, 174, 203, 232, 261, 290, 319, 348, 377, 406, 435, 464, 493, 522, 551, 580, 609, 638, 667, 696, 725, 754, 783, 812, 841, 870, 899, 928, 957, 986, 1015, 1044, 1073, 1102, 1131, 1160, 1189, 1218, 1247, 1276, 1305, 1334, 1363, 1392, 1421, 1450, 1479, 1508, 1537, 1566, 1595, 1624, 1653, 1682, 1711
Multiples of 57: 57, 114, 171, 228, 285, 342, 399, 456, 513, 570, 627, 684, 741, 798, 855, 912, 969, 1026, 1083, 1140, 1197, 1254, 1311, 1368, 1425, 1482, 1539, 1596, 1653, 1710, 1767
So the LCM for 29 and 57 is 1,653
Finding LCM for 29 and 57 by Prime Factorization
Another method to find LCM for numbers 29 and 57 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
