Least Common Multiple (LCM) of 287 and 295 with the help of Prime Factorisation
One method for determining the LCM of 287 and 295 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 287's prime factorization:
| 7 | 287 |
| 41 | 41 |
| 1 |
Prime factors of 287 are 7,41.
287 = 71×411
And this is 295's prime factorization:
| 5 | 295 |
| 59 | 59 |
| 1 |
Prime factors of 295 are 5,59.
295 = 51×591
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: 7,41, 5,59
.51×71×411×591 = 84665
This shows that the LCM of 287 and 295 is 84665.
How to Calculate the LCM of 287 and 295 Using Common Multiples
