Least Common Multiple (LCM) of 351 and 355 with the help of Prime Factorisation
One method for determining the LCM of 351 and 355 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 351's prime factorization:
| 3 | 351 |
| 3 | 117 |
| 3 | 39 |
| 13 | 13 |
| 1 |
Prime factors of 351 are 3,13.
351 = 33×131
And this is 355's prime factorization:
| 5 | 355 |
| 71 | 71 |
| 1 |
Prime factors of 355 are 5,71.
355 = 51×711
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: 3,13, 5,71
.33×51×131×711 = 124605
This shows that the LCM of 351 and 355 is 124605.
How to Calculate the LCM of 351 and 355 Using Common Multiples
