LCM for 39 and 41
What's the Least Common Multiple (LCM) of 39 and 41?
Answer
(One thousand, five hundred ninety-nine)
Finding LCM for 39 and 41 using GCF of these numbers
The first method to find LCM for numbers 39 and 41 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 39 and 41 is 1, so
LCM = (39 × 41) ÷ 1
LCM = 1599 ÷ 1
LCM = 1599
Finding LCM for 39 and 41 by Listing Multiples
The second method to find LCM for numbers 39 and 41 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 39: 39, 78, 117, 156, 195, 234, 273, 312, 351, 390, 429, 468, 507, 546, 585, 624, 663, 702, 741, 780, 819, 858, 897, 936, 975, 1014, 1053, 1092, 1131, 1170, 1209, 1248, 1287, 1326, 1365, 1404, 1443, 1482, 1521, 1560, 1599, 1638, 1677
Multiples of 41: 41, 82, 123, 164, 205, 246, 287, 328, 369, 410, 451, 492, 533, 574, 615, 656, 697, 738, 779, 820, 861, 902, 943, 984, 1025, 1066, 1107, 1148, 1189, 1230, 1271, 1312, 1353, 1394, 1435, 1476, 1517, 1558, 1599, 1640, 1681
So the LCM for 39 and 41 is 1599
Finding LCM for 39 and 41 by Prime Factorization
Another method to find LCM for numbers 39 and 41 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 39: 3, 13 (exponent form: 31, 131)
All Prime Factors of 41: 41 (exponent form: 411)
31 × 131 × 411 = 1599
