Least Common Multiple (LCM) of 116 and 120 with the help of Prime Factorisation
One method for determining the LCM of 116 and 120 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 116's prime factorization:
| 2 | 116 |
| 2 | 58 |
| 29 | 29 |
| 1 |
Prime factors of 116 are 2,29.
116 = 22×291
And this is 120's prime factorization:
| 2 | 120 |
| 2 | 60 |
| 2 | 30 |
| 3 | 15 |
| 5 | 5 |
| 1 |
Prime factors of 120 are 2, 3,5.
120 = 23×31×51
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: 2,29, 3,5
.23×31×51×291 = 3480
This shows that the LCM of 116 and 120 is 3480.
How to Calculate the LCM of 116 and 120 Using Common Multiples
