How-to: What is the LCM of 250 and 304?
The below solved example with step by step work shows how to find what is the lcm of 250 and 304 by using prime factors method and division method.
Solved example using prime factors method:
What is the LCM of 250 and 304?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 250
B = 304
What to be found:
find the lcm of 250 and 304
step 2 Find the prime factors of 250 and 304:
Prime factors of 250 = 2 x 5 x 5 x 5
Prime factors of 304 = 2 x 2 x 2 x 2 x 19
