LCM for 2 and 64
What's the Least Common Multiple (LCM) of 2 and 64?
(Sixty-four)
Finding LCM for 2 and 64 using GCF's of these numbers
The first method to find LCM for numbers 2 and 64 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 2 and 64 is 2, so
LCM = (2 × 64) ÷ 2
LCM = 128 ÷ 2
LCM = 64
Finding LCM for 2 and 64 by Listing Multiples
The second method to find LCM for numbers 2 and 64 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68
Multiples of 64: 64, 128, 192, 256, 320, 384, 448, 512, 576, 640, 704, 768, 832, 896, 960, 1024, 1088, 1152, 1216, 1280, 1344, 1408, 1472, 1536, 1600, 1664, 1728, 1792, 1856, 1920, 1984, 2048, 2112, 2176, [...], 64
So the LCM for 2 and 64 is 64
Finding LCM for 2 and 64 by Prime Factorization
Another method to find LCM for numbers 2 and 64 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 2: 2 (exponent form: 21)
All Prime Factors of 64: 2, 2, 2, 2, 2, 2 (exponent form: 26)
26 = 64
