How-to: What is the LCM of 6 and 256?
The below solved example with step by step work shows how to find what is the lcm of 6 and 256 by using prime factors method and division method.
Solved example using prime factors method:
What is the LCM of 6 and 256?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 6
B = 256
What to be found:
find the lcm of 6 and 256
step 2 Find the prime factors of 6 and 256:
Prime factors of 6 = 2 x 3
Prime factors of 256 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2
