Find LCM of 405,951,494,855 with Prime Factorization
| 3 | 405, 951, 494, 855 |
| 3 | 135, 317, 494, 285 |
| 5 | 45, 317, 494, 95 |
| 19 | 9, 317, 494, 19 |
| 9, 317, 26, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 19 x 9 x 317 x 26 x 1 = 63422190
Therefore, the lowest common multiple of 405,951,494,855 is 63422190.
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.
405 x 951 x 494 x 855 = 162677917350
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
951 : 1, 3, 317, 951
494 : 1, 2, 13, 19, 26, 38, 247, 494
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,951,494,855, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
951:3x 317
494:2x 13x 19
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 19 = 2565
Therefore, the value for common factors is 2565.
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 = 162677917350/(1x2565)
LCM = 162677917350/2565
LCM = 63422190
Thus, we can understand that the LCM of 405,951,494,855 is 63422190.
