LCM for 27 and 49
What's the Least Common Multiple (LCM) of 27 and 49?
Answer
(One thousand, three hundred twenty-three)
Finding LCM for 27 and 49 using GCF of these numbers
The first method to find LCM for numbers 27 and 49 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 27 and 49 is 1, so
LCM = (27 × 49) ÷ 1
LCM = 1323 ÷ 1
LCM = 1323
Finding LCM for 27 and 49 by Listing Multiples
The second method to find LCM for numbers 27 and 49 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 27: 27, 54, 81, 108, 135, 162, 189, 216, 243, 270, 297, 324, 351, 378, 405, 432, 459, 486, 513, 540, 567, 594, 621, 648, 675, 702, 729, 756, 783, 810, 837, 864, 891, 918, 945, 972, 999, 1026, 1053, 1080, 1107, 1134, 1161, 1188, 1215, 1242, 1269, 1296, 1323, 1350, 1377
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
So the LCM for 27 and 49 is 1323
Finding LCM for 27 and 49 by Prime Factorization
