LCM of 3, 13 and 39 is equal to 39. The comprehensive work provides more insight of how to find what is the lcm of 3, 13 and 39 by using prime factors and special division methods, and the example use case of mathematics and real world problems.
what is the lcm of 3, 13 and 39?
lcm (3 13 39) = (?)
3 => 3
13 => 13
39 => 3 x 13
= 3 x 13
= 39
lcm (3, 13 and 39) = 39
39 is the lcm of 3, 13 and 39.
where,
3 is a positive integer,
13 is a positive integer,
39 is the lcm of 3, 13 and 39,
{3, 13} in {3, 13, 3 x 13} are the most repeated factors of 3, 13 and 39,
There is no non-repeated factors of 3, 13 and 39 in {3, 13, 3 x 13}.

The below solved example with step by step work shows how to find what is the lcm of 3, 13 and 39 by using either prime factors method and special division method.
Solved example using prime factors method:
What is the LCM of 3, 13 and 39?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 3
B = 13
C = 39
What to be found:
find the lcm of 3, 13 and 39
step 2 Find the prime factors of 3, 13 and 39:
Prime factors of 3 = 3
Prime factors of 13 = 13
Prime factors of 39 = 3 x 13
step 3 Identify the repeated and non-repeated prime factors of 3, 13 and 39:
{3, 13} are the most repeated factors and there is no non-repeated factors of 3, 13 and 39.
step 4 Find the product of repeated and non-repeated prime factors of 3, 13 and 39:
= 3 x 13
= 39
lcm(20 and 30) = 39
Hence,
lcm of 3, 13 and 39 is 39
