LCM for 16 and 128
What's the Least Common Multiple (LCM) of 16 and 128?
Answer
(One hundred twenty-eight)
Finding LCM for 16 and 128 using GCF of these numbers
The first method to find LCM for numbers 16 and 128 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 16 and 128 is 16, so
LCM = (16 × 128) ÷ 16
LCM = 2,048 ÷ 16
LCM = 128
Finding LCM for 16 and 128 by Listing Multiples
The second method to find LCM for numbers 16 and 128 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 16: 16, 32, 48, 64, 80, 96, 112, 128, 144, 160
Multiples of 128: 128, 256, 384
So the LCM for 16 and 128 is 128
Finding LCM for 16 and 128 by Prime Factorization
Another method to find LCM for numbers 16 and 128 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 16: 2, 2, 2, 2 (exponent form: 24)
All Prime Factors of 128: 2, 2, 2, 2, 2, 2, 2 (exponent form: 27)
27 = 128
