what is the lcm of 6, 15 and 25?
lcm (6 15 25) = (?)
6 => 2 x 3
15 => 3 x 5
25 => 5 x 5
= 3 x 5 x 2 x 5
= 150
lcm (6, 15 and 25) = 150
150 is the lcm of 6, 15 and 25.
where,
6 is a positive integer,
15 is a positive integer,
150 is the lcm of 6, 15 and 25,
{3, 5} in {2 x 3, 3 x 5, 5 x 5} are the most repeated factors of 6, 15 and 25,
{2, 5} in {2 x 3, 3 x 5, 5 x 5} are the the other remaining factors of 6, 15 and 25.

The below solved example with step by step work shows how to find what is the lcm of 6, 15 and 25 by using either prime factors method and special division method.
Solved example using prime factors method:
What is the LCM of 6, 15 and 25?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 6
B = 15
C = 25
What to be found:
find the lcm of 6, 15 and 25
step 2 Find the prime factors of 6, 15 and 25:
Prime factors of 6 = 2 x 3
Prime factors of 15 = 3 x 5
Prime factors of 25 = 5 x 5
step 3 Identify the repeated and non-repeated prime factors of 6, 15 and 25:
{3, 5} are the most repeated factors and {2, 5} are the non-repeated factors of 6, 15 and 25.
step 4 Find the product of repeated and non-repeated prime factors of 6, 15 and 25:
= 3 x 5 x 2 x 5
= 150
lcm(20 and 30) = 150
Hence,
lcm of 6, 15 and 25 is 150
