LCM for 9 and 64
What's the Least Common Multiple (LCM) of 9 and 64?
(Five hundred seventy-six)
Finding LCM for 9 and 64 using GCF's of these numbers
The first method to find LCM for numbers 9 and 64 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 9 and 64 is 1, so
LCM = (9 × 64) ÷ 1
LCM = 576 ÷ 1
LCM = 576
Finding LCM for 9 and 64 by Listing Multiples
The second method to find LCM for numbers 9 and 64 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180, 189, 198, 207, 216, 225, 234, 243, 252, 261, 270, 279, 288, 297, 306, 315, 324, 333, 342, 351, 360, 369, 378, 387, 396, 405, 414, 423, 432, 441, 450, 459, 468, 477, 486, 495, 504, 513, 522, 531, 540, 549, 558, 567, 576, 585, 594
Multiples of 64: 64, 128, 192, 256, 320, 384, 448, 512, 576, 640, 704
So the LCM for 9 and 64 is 576
