LCM for 36 and 49
What's the Least Common Multiple (LCM) of 36 and 49?
(One thousand, seven hundred sixty-four)
Finding LCM for 36 and 49 using GCF's of these numbers
The first method to find LCM for numbers 36 and 49 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 36 and 49 is 1, so
LCM = (36 × 49) ÷ 1
LCM = 1764 ÷ 1
LCM = 1764
Finding LCM for 36 and 49 by Listing Multiples
The second method to find LCM for numbers 36 and 49 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 36: 36, 72, 108, 144, 180, 216, 252, 288, 324, 360, 396, 432, 468, 504, 540, 576, 612, 648, 684, 720, 756, 792, 828, 864, 900, 936, 972, 1008, 1044, 1080, 1116, 1152, 1188, 1224, 1260, 1296, 1332, 1368, 1404, 1440, 1476, 1512, 1548, 1584, 1620, 1656, 1692, 1728, 1764, 1800, 1836
Multiples of 49: 49, 98, 147, 196, 245, 294, 343, 392, 441, 490, 539, 588, 637, 686, 735, 784, 833, 882, 931, 980, 1029, 1078, 1127, 1176, 1225, 1274, 1323, 1372, 1421, 1470, 1519, 1568, 1617, 1666, 1715, 1764, 1813, 1862
So the LCM for 36 and 49 is 1764
Finding LCM for 36 and 49 by Prime Factorization
Another method to find LCM for numbers 36 and 49 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 36: 2, 2, 3, 3 (exponent form: 22, 32)
All Prime Factors of 49: 7, 7 (exponent form: 72)
