How-to: What is the LCM of 100 and 103?
The below solved example with step by step work shows how to find what is the lcm of 100 and 103 by using prime factors method and division method.
Solved example using prime factors method:
What is the LCM of 100 and 103?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 100
B = 103
What to be found:
find the lcm of 100 and 103
step 2 Find the prime factors of 100 and 103:
Prime factors of 100 = 2 x 2 x 5 x 5
Prime factors of 103 = 103
step 3Identify the repeated and non-repeated prime factors of 100 and 103:
Since there is no common factors between 100 and 103, multiplying the given numbers directly provides the LCM of
100 and 103.
= 100 x 103
= 10300
lcm(100 and 103) = 10300
Hence,
lcm of 100 and 103 is 10300
This special division method is one of the easiest ways to understand the entire calculation to find the LCM of 100 and 103.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 100 and 103
What to be found:
lcm (100, 103) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
100 and 103
step 3 Choose the divisor which divides each or most of the given integers (100 and 103), divide each integers separately and write down the quotient in the next line right under the respective integers. Bring down the integer to the next line if any integer in 100 and 103 is not divisible by the selected divisor; repeat the same process until all the integers are brought to 1 as like below:
| 2 | 100 | 103 |
| 2 | 50 | 103 |
| 5 | 25 | 103 |
| 5 | 5 | 103 |
| 103 | 1 | 103 |
| 1 | 1 |
step 4 Multiply the divisors to find the lcm of 100 and 103:
= 2 x 2 x 5 x 5 x 103
= 10300
LCM(100, 103) = 10300
The LCM of two numbers 100 and 103 is 10300
