Least Common Multiple (LCM) of 235 and 242 with the help of Prime Factorisation
One method for determining the LCM of 235 and 242 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 235's prime factorization:
| 5 | 235 |
| 47 | 47 |
| 1 |
Prime factors of 235 are 5,47.
235 = 51×471
And this is 242's prime factorization:
| 2 | 242 |
| 11 | 121 |
| 11 | 11 |
| 1 |
Prime factors of 242 are 2,11.
242 = 21×112
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: 5,47, 2,11
.21×51×112×471 = 56870
This shows that the LCM of 235 and 242 is 56870.
How to Calculate the LCM of 235 and 242 Using Common Multiples
