Find LCM of 510,916,690,780,857 with Prime Factorization
| 2 | 510, 916, 690, 780, 857 |
| 2 | 255, 458, 345, 390, 857 |
| 3 | 255, 229, 345, 195, 857 |
| 5 | 85, 229, 115, 65, 857 |
| 17, 229, 23, 13, 857 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 17 x 229 x 23 x 13 x 857 = 59853239940
Therefore, the lowest common multiple of 510,916,690,780,857 is 59853239940.
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.
510 x 916 x 690 x 780 x 857 = 215471663784000
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.
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
916 : 1, 2, 4, 229, 458, 916
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 510,916,690,780,857, is 1.
Now, the common factors can be found like this.
510:2x 3x 5x 17
916:2x 2x 229
690:2x 3x 5x 23
780:2x 2x 3x 5x 13
857:857
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 2x 2x 3x 3x 5x 5 = 3600
Therefore, the value for common factors is 3600.
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 = 215471663784000/(1x3600)
LCM = 215471663784000/3600
LCM = 59853239940
Thus, we can understand that the LCM of 510,916,690,780,857 is 59853239940.
