What is LCM of 100 and 104
Given Numbers are 100, 104
We can find the LCM of 100, 104 using the brute force method, prime factorization method, or GCD method.
To use brute force method, list the multiples of 100 and 104
Multiples of 100 =100,200,300,400,500,600,700,800,900,1000,1100,1200,1300,1400,1500,1600,1700,
Multiples of 104 =104,208,312,416,520,624,728,832,936,1040,1144,1248,1352,1456,1560,1664,1768,
Now, get the least common multiple of 100, 104 which is 2600
So, the LCM of 100, 104 is 2600.
Least Common Multiple (LCM) of 100 and 104 with the help of Prime Factorisation
One method for determining the LCM of 100 and 104 is to compare the prime factorization of each number. You can find the prime factorization for each number by following the instructions below:
Here is 100's prime factorization:
| 2 | 100 |
| 2 | 50 |
| 5 | 25 |
| 5 | 5 |
| 1 |
Prime factors of 100 are 2,5.
100 = 22×52
And this is 104's prime factorization:
| 2 | 104 |
| 2 | 52 |
| 2 | 26 |
| 13 | 13 |
| 1 |
Prime factors of 104 are 2,13.
104 = 23×131
When comparing the prime factorization of these two numbers, look for the highest power to which each prime factor is raised. In this case, the following primary factors must be considered: 2,5,13
.23×52×131 = 2600
This shows that the LCM of 100 and 104 is 2600.
How to Calculate the LCM of 100 and 104 Using Common Multiples
The first step in determining the Least Common Multiple of 100 and 104 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 100 and 104:
Lets look at the first ten multiples of these numbers, 100 and 104:
100,200,300,400,500,600,700,800,900,1700 are the first ten multiples of 100.
104,208,312,416,520,624,728,832,936,1768 are the first ten multiples of 104.
You can continue to list the multiples of these numbers until you find a match. Once you have found a match, or several matches, the Least Common Multiple is the smallest of these matches. The first matching multiple(s) of 100 and 104, for example, are 1200, 1700, and 1664. 2600 is the least common multiple since it is the smallest.
100 and 104 have an LCM of 2600.
Least Common Multiple of 100 and 104 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 100 and 104, than apply into the LCM equation.
GCF(100,104) = 4
LCM(100,104) = ( 100 × 104) / 4
LCM(100,104) = 10400 / 4
LCM(100,104) = 2600
