Least Common Multiple (LCM) of 240 and 244 with the help of Prime Factorisation
One method for determining the LCM of 240 and 244 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 240's prime factorization:
| 2 | 240 |
| 2 | 120 |
| 2 | 60 |
| 2 | 30 |
| 3 | 15 |
| 5 | 5 |
| 1 |
Prime factors of 240 are 2, 3,5.
240 = 24×31×51
And this is 244's prime factorization:
| 2 | 244 |
| 2 | 122 |
| 61 | 61 |
| 1 |
Prime factors of 244 are 2,61.
244 = 22×611
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, 3,5,61
.24×31×51×611 = 14640
This shows that the LCM of 240 and 244 is 14640.
