what is the lcm of 36, 60 and 80?
lcm (36 60 80) = (?)
36 => 2 x 2 x 3 x 3
60 => 2 x 2 x 3 x 5
80 => 2 x 2 x 2 x 2 x 5
= 2 x 2 x 3 x 5 x 3 x 2 x 2
= 720
lcm (36, 60 and 80) = 720
720 is the lcm of 36, 60 and 80.
where,
36 is a positive integer,
60 is a positive integer,
720 is the lcm of 36, 60 and 80,
{2, 2, 3, 5} in {2 x 2 x 3 x 3, 2 x 2 x 3 x 5, 2 x 2 x 2 x 2 x 5} are the most repeated factors of 36, 60 and 80,
{3, 2, 2} in {2 x 2 x 3 x 3, 2 x 2 x 3 x 5, 2 x 2 x 2 x 2 x 5} are the the other remaining factors of 36, 60 and 80.

The below solved example with step by step work shows how to find what is the lcm of 36, 60 and 80 by using either prime factors method and special division method.
Solved example using prime factors method:
What is the LCM of 36, 60 and 80?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 36
B = 60
C = 80
What to be found:
find the lcm of 36, 60 and 80
step 2 Find the prime factors of 36, 60 and 80:
Prime factors of 36 = 2 x 2 x 3 x 3
Prime factors of 60 = 2 x 2 x 3 x 5
Prime factors of 80 = 2 x 2 x 2 x 2 x 5
step 3 Identify the repeated and non-repeated prime factors of 36, 60 and 80:
{2, 2, 3, 5} are the most repeated factors and {3, 2, 2} are the non-repeated factors of 36, 60 and 80.
step 4 Find the product of repeated and non-repeated prime factors of 36, 60 and 80:
= 2 x 2 x 3 x 5 x 3 x 2 x 2
= 720
lcm(20 and 30) = 720
Hence,
lcm of 36, 60 and 80 is 720
