LCM for 37 and 40
What's the Least Common Multiple (LCM) of 37 and 40?
Answer
(One thousand, four hundred eighty)
Finding LCM for 37 and 40 using GCF of these numbers
The first method to find LCM for numbers 37 and 40 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 37 and 40 is 1, so
LCM = (37 × 40) ÷ 1
LCM = 1480 ÷ 1
LCM = 1480
Finding LCM for 37 and 40 by Listing Multiples
The second method to find LCM for numbers 37 and 40 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 37: 37, 74, 111, 148, 185, 222, 259, 296, 333, 370, 407, 444, 481, 518, 555, 592, 629, 666, 703, 740, 777, 814, 851, 888, 925, 962, 999, 1036, 1073, 1110, 1147, 1184, 1221, 1258, 1295, 1332, 1369, 1406, 1443, 1480, 1517, 1554
Multiples of 40: 40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440, 480, 520, 560, 600, 640, 680, 720, 760, 800, 840, 880, 920, 960, 1000, 1040, 1080, 1120, 1160, 1200, 1240, 1280, 1320, 1360, 1400, 1440, 1480, 1520, 1560
So the LCM for 37 and 40 is 1480
Finding LCM for 37 and 40 by Prime Factorization
Another method to find LCM for numbers 37 and 40 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 37: 37 (exponent form: 371)
All Prime Factors of 40: 2, 2, 2, 5 (exponent form: 23, 51)
371 × 23 × 51 = 1480
