Least Common Multiple (LCM) of 311 and 315 with the help of Prime Factorisation
One method for determining the LCM of 311 and 315 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 311's prime factorization:
| 311 | 311 |
| 1 |
Prime factors of 311 are 311.
311 = 3111
And this is 315's prime factorization:
| 3 | 315 |
| 3 | 105 |
| 5 | 35 |
| 7 | 7 |
| 1 |
Prime factors of 315 are 3, 5,7.
315 = 32×51×71
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:311, 3, 5,7
.32×51×71×3111 = 97965
This shows that the LCM of 311 and 315 is 97965.
How to Calculate the LCM of 311 and 315 Using Common Multiples
