Least Common Multiple (LCM) of 230 and 238 with the help of Prime Factorisation
One method for determining the LCM of 230 and 238 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 230's prime factorization:
| 2 | 230 |
| 5 | 115 |
| 23 | 23 |
| 1 |
Prime factors of 230 are 2, 5,23.
230 = 21×51×231
And this is 238's prime factorization:
| 2 | 238 |
| 7 | 119 |
| 17 | 17 |
| 1 |
Prime factors of 238 are 2, 7,17.
238 = 21×71×171
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, 5,23, 7,17
.21×51×71×171×231 = 27370
This shows that the LCM of 230 and 238 is 27370.
How to Calculate the LCM of 230 and 238 Using Common Multiples
