What's the Least Common Multiple (LCM) of 8 and 77?
(Six hundred sixteen)
Finding LCM for 8 and 77 using GCF's of these numbers
The first method to find LCM for numbers 8 and 77 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 8 and 77 is 1, so
LCM = (8 × 77) ÷ 1
LCM = 616 ÷ 1
LCM = 616
Finding LCM for 8 and 77 by Listing Multiples
The second method to find LCM for numbers 8 and 77 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128, 136, 144, 152, 160, 168, 176, 184, 192, 200, 208, 216, 224, 232, 240, 248, 256, 264, 272, 280, 288, 296, 304, 312, 320, 328, 336, 344, 352, 360, 368, 376, 384, 392, 400, 408, 416, 424, 432, 440, 448, 456, 464, 472, 480, 488, 496, 504, 512, 520, 528, 536, 544, 552, 560, 568, 576, 584, 592, 600, 608, 616, 624, 632
Multiples of 77: 77, 154, 231, 308, 385, 462, 539, 616, 693, 770
So the LCM for 8 and 77 is 616
