What's the Least Common Multiple (LCM) of 27 and 32?
(Eight hundred sixty-four)
Finding LCM for 27 and 32 using GCF's of these numbers
The first method to find LCM for numbers 27 and 32 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 27 and 32 is 1, so
LCM = (27 × 32) ÷ 1
LCM = 864 ÷ 1
LCM = 864
Finding LCM for 27 and 32 by Listing Multiples
The second method to find LCM for numbers 27 and 32 is to list out the common multiples for both nubmers and pick the first which matching:
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
Multiples of 32: 32, 64, 96, 128, 160, 192, 224, 256, 288, 320, 352, 384, 416, 448, 480, 512, 544, 576, 608, 640, 672, 704, 736, 768, 800, 832, 864, 896, 928
So the LCM for 27 and 32 is 864
