Given numbers are 331,205,355,287
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 331,205,355,287 is 33723935.
Find LCM of 331,205,355,287 with Prime Factorization
| 5 | 331, 205, 355, 287 |
| 41 | 331, 41, 71, 287 |
| 331, 1, 71, 7 |
Multiply the prime numbers at the bottom and the left side.
5 x 41 x 331 x 1 x 71 x 7 = 33723935
Therefore, the lowest common multiple of 331,205,355,287 is 33723935.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
331 x 205 x 355 x 287 = 6913406675
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
331 : 1, 331
205 : 1, 5, 41, 205
355 : 1, 5, 71, 355
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,205,355,287, is 1.
Now, the common factors can be found like this.
331:331
205:5x 41
355:5x 71
287:7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 41 = 205
Therefore, the value for common factors is 205.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 6913406675/(1x205)
LCM = 6913406675/205
LCM = 33723935
Thus, we can understand that the LCM of 331,205,355,287 is 33723935.
