The LCM of 704,902,400,857 is 618411200.
Find LCM of 704,902,400,857 with Prime Factorization
| 2 | 704, 902, 400, 857 |
| 2 | 352, 451, 200, 857 |
| 2 | 176, 451, 100, 857 |
| 2 | 88, 451, 50, 857 |
| 11 | 44, 451, 25, 857 |
| 4, 41, 25, 857 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 11 x 4 x 41 x 25 x 857 = 618411200
Therefore, the lowest common multiple of 704,902,400,857 is 618411200.
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.
704 x 902 x 400 x 857 = 217680742400
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.
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
902 : 1, 2, 11, 22, 41, 82, 451, 902
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 704,902,400,857, is 1.
Now, the common factors can be found like this.
704:2x 2x 2x 2x 2x 2x 11
902:2x 11x 41
400:2x 2x 2x 2x 5x 5
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 2x 11 = 352
Therefore, the value for common factors is 352.
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 = 217680742400/(1x352)
LCM = 217680742400/352
LCM = 618411200
Thus, we can understand that the LCM of 704,902,400,857 is 618411200.
