Find LCM of 330,455,287,454,231 with Prime Factorization
| 2 | 330, 455, 287, 454, 231 |
| 3 | 165, 455, 287, 227, 231 |
| 5 | 55, 455, 287, 227, 77 |
| 7 | 11, 91, 287, 227, 77 |
| 11 | 11, 13, 41, 227, 11 |
| 1, 13, 41, 227, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 11 x 1 x 13 x 41 x 227 x 1 = 279489210
Therefore, the lowest common multiple of 330,455,287,454,231 is 279489210.
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.
330 x 455 x 287 x 454 x 231 = 4519340525700
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.
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
455 : 1, 5, 7, 13, 35, 65, 91, 455
287 : 1, 7, 41, 287
454 : 1, 2, 227, 454
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 330,455,287,454,231, is 1.
Now, the common factors can be found like this.
330:2x 3x 5x 11
455:5x 7x 13
287:7x 41
454:2x 227
231:3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7x 7x 11 = 16170
Therefore, the value for common factors is 16170.
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 = 4519340525700/(1x16170)
LCM = 4519340525700/16170
LCM = 279489210
Thus, we can understand that the LCM of 330,455,287,454,231 is 279489210.
