what is the lcm of 4, 8 and 12?
lcm (4 8 12) = (?)
4 => 2 x 2
8 => 2 x 2 x 2
12 => 2 x 2 x 3
= 2 x 2 x 2 x 3
= 24
lcm (4, 8 and 12) = 24
24 is the lcm of 4, 8 and 12.
where,
4 is a positive integer,
8 is a positive integer,
24 is the lcm of 4, 8 and 12,
{2, 2} in {2 x 2, 2 x 2 x 2, 2 x 2 x 3} are the most repeated factors of 4, 8 and 12,
{2, 3} in {2 x 2, 2 x 2 x 2, 2 x 2 x 3} are the the other remaining factors of 4, 8 and 12.
Use in Mathematics: LCM of 4, 8 and 12
The below are some of the mathematical applications where lcm of 4, 8 and 12 can be used:
The below solved example with step by step work shows how to find what is the lcm of 4, 8 and 12 by using either prime factors method and special division method.
Solved example using prime factors method:
What is the LCM of 4, 8 and 12?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 4
B = 8
C = 12
What to be found:
find the lcm of 4, 8 and 12
step 2 Find the prime factors of 4, 8 and 12:
Prime factors of 4 = 2 x 2
Prime factors of 8 = 2 x 2 x 2
Prime factors of 12 = 2 x 2 x 3
step 3 Identify the repeated and non-repeated prime factors of 4, 8 and 12:
{2, 2} are the most repeated factors and {2, 3} are the non-repeated factors of 4, 8 and 12.
step 4 Find the product of repeated and non-repeated prime factors of 4, 8 and 12:
= 2 x 2 x 2 x 3
= 24
lcm(20 and 30) = 24
Hence,
lcm of 4, 8 and 12 is 24
