Find LCM of 858,663,916,787,605 with Prime Factorization
| 2 | 858, 663, 916, 787, 605 |
| 3 | 429, 663, 458, 787, 605 |
| 11 | 143, 221, 458, 787, 605 |
| 13 | 13, 221, 458, 787, 55 |
| 1, 17, 458, 787, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 1 x 17 x 458 x 787 x 55 = 289160594580
Therefore, the lowest common multiple of 858,663,916,787,605 is 289160594580.
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.
858 x 663 x 916 x 787 x 605 = 248099790149640
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
663 : 1, 3, 13, 17, 39, 51, 221, 663
916 : 1, 2, 4, 229, 458, 916
787 : 1, 787
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,663,916,787,605, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
663:3x 13x 17
916:2x 2x 229
787:787
605:5x 11x 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 11x 13 = 858
Therefore, the value for common factors is 858.
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 = 248099790149640/(1x858)
LCM = 248099790149640/858
LCM = 289160594580
Thus, we can understand that the LCM of 858,663,916,787,605 is 289160594580.
