Least Common Multiple (LCM) of 251 and 258 with the help of Prime Factorisation
One method for determining the LCM of 251 and 258 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 251's prime factorization:
| 251 | 251 |
| 1 |
Prime factors of 251 are 251.
251 = 2511
And this is 258's prime factorization:
| 2 | 258 |
| 3 | 129 |
| 43 | 43 |
| 1 |
Prime factors of 258 are 2, 3,43.
258 = 21×31×431
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:251, 2, 3,43
.21×31×431×2511 = 64758
This shows that the LCM of 251 and 258 is 64758.
How to Calculate the LCM of 251 and 258 Using Common Multiples
