LCM for 64 and 128
What's the Least Common Multiple (LCM) of 64 and 128?
(One hundred twenty-eight)
Finding LCM for 64 and 128 using GCF's of these numbers
The first method to find LCM for numbers 64 and 128 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 64 and 128 is 64, so
LCM = (64 × 128) ÷ 64
LCM = 8192 ÷ 64
LCM = 128
Finding LCM for 64 and 128 by Listing Multiples
The second method to find LCM for numbers 64 and 128 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 64: 64, 128, 192, 256
Multiples of 128: 128, 256, 384, 512, 640, 768, 896, 1024, 1152, 1280, 1408, 1536, 1664, 1792, 1920, 2048, 2176, 2304, 2432, 2560, 2688, 2816, 2944, 3072, 3200, 3328, 3456, 3584, 3712, 3840, 3968,
