Find LCM of 317,675,991,405,787 with Prime Factorization
| 3 | 317, 675, 991, 405, 787 |
| 3 | 317, 225, 991, 135, 787 |
| 3 | 317, 75, 991, 45, 787 |
| 5 | 317, 25, 991, 15, 787 |
| 317, 5, 991, 3, 787 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 317 x 5 x 991 x 3 x 787 = 500648220225
Therefore, the lowest common multiple of 317,675,991,405,787 is 500648220225.
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.
317 x 675 x 991 x 405 x 787 = 67587509730375
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.
317 : 1, 317
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
991 : 1, 991
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
787 : 1, 787
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 317,675,991,405,787, is 1.
Now, the common factors can be found like this.
317:317
675:3x 3x 3x 5x 5
991:991
405:3x 3x 3x 3x 5
787:787
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 5 = 135
Therefore, the value for common factors is 135.
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 = 67587509730375/(1x135)
LCM = 67587509730375/135
LCM = 500648220225
Thus, we can understand that the LCM of 317,675,991,405,787 is 500648220225.
