LCM of 1 and 8 is equal to 8. The comprehensive work provides more insight of how to find what is the lcm of 1 and 8 by using prime factors and special division methods, and the example use case of mathematics and real world problems.
what is the lcm of 1 and 8?
lcm (1 8) = (?)
1 => 1
8 => 2 x 2 x 2
= 1 x 2 x 2 x 2
= 8
lcm (1 and 8) = 8
8 is the lcm of 1 and 8.
where,
1 is a positive integer,
8 is a positive integer,
8 is the lcm of 1 and 8,
There is no common factors of 1 and 8 in {1, 2 x 2 x 2},
{1 x 2 x 2 x 2} in {1, 2 x 2 x 2} are the uncommon factors of 1 and 8.
Use in Mathematics: LCM of 1 and 8
The below are some of the mathematical applications where lcm of 1 and 8 can be used:
The below solved example with step by step work shows how to find what is the lcm of 1 and 8 by using prime factors method and division method.
Solved example using prime factors method:
What is the LCM of 1 and 8?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 1
B = 8
What to be found:
find the lcm of 1 and 8
step 2 Find the prime factors of 1 and 8:
Prime factors of 1 = 1
Prime factors of 8 = 2 x 2 x 2
step 3Identify the repeated and non-repeated prime factors of 1 and 8:
Since there is no common factors between 1 and 8, multiplying the given numbers directly provides the LCM of
1 and 8.
= 1 x 8
= 8
lcm(1 and 8) = 8
Hence,
lcm of 1 and 8 is 8
