Find LCM of 459,435,391,788,172 with Prime Factorization
| 2 | 459, 435, 391, 788, 172 |
| 2 | 459, 435, 391, 394, 86 |
| 3 | 459, 435, 391, 197, 43 |
| 17 | 153, 145, 391, 197, 43 |
| 9, 145, 23, 197, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 9 x 145 x 23 x 197 x 43 = 51868441260
Therefore, the lowest common multiple of 459,435,391,788,172 is 51868441260.
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.
459 x 435 x 391 x 788 x 172 = 10581162017040
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.
459 : 1, 3, 9, 17, 27, 51, 153, 459
435 : 1, 3, 5, 15, 29, 87, 145, 435
391 : 1, 17, 23, 391
788 : 1, 2, 4, 197, 394, 788
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 459,435,391,788,172, is 1.
Now, the common factors can be found like this.
459:3x 3x 3x 17
435:3x 5x 29
391:17x 23
788:2x 2x 197
172:2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 17 = 204
Therefore, the value for common factors is 204.
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 = 10581162017040/(1x204)
LCM = 10581162017040/204
LCM = 51868441260
Thus, we can understand that the LCM of 459,435,391,788,172 is 51868441260.
