How-to: What is the LCM of 8, 24 and 32?
The below solved example with step by step work shows how to find what is the lcm of 8, 24 and 32 by using either prime factors method and special division method.
Solved example using prime factors method:
What is the LCM of 8, 24 and 32?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 8
B = 24
C = 32
What to be found:
find the lcm of 8, 24 and 32
step 2 Find the prime factors of 8, 24 and 32:
Prime factors of 8 = 2 x 2 x 2
Prime factors of 24 = 2 x 2 x 2 x 3
Prime factors of 32 = 2 x 2 x 2 x 2 x 2

{2, 2, 2} are the most repeated factors and {3, 2, 2} are the non-repeated factors of 8, 24 and 32.
step 4 Find the product of repeated and non-repeated prime factors of 8, 24 and 32:
= 2 x 2 x 2 x 3 x 2 x 2
= 96
lcm(20 and 30) = 96
Hence,
lcm of 8, 24 and 32 is 96
This special division method is the easiest way to understand the entire calculation of what is the lcm of 8, 24 and 32.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 8, 24 and 32
What to be found:
lcm (8, 24, 32) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
8, 24 and 32
step 3 Choose the divisor which divides each or most of the given integers (8, 24 and 32), divide each integers separately and write down the quotient in the next line right under the respective integers.
