Find LCM of 704,678,330,400,810 with Prime Factorization
| 2 | 704, 678, 330, 400, 810 |
| 2 | 352, 339, 165, 200, 405 |
| 2 | 176, 339, 165, 100, 405 |
| 2 | 88, 339, 165, 50, 405 |
| 3 | 44, 339, 165, 25, 405 |
| 5 | 44, 113, 55, 25, 135 |
| 11 | 44, 113, 11, 5, 27 |
| 4, 113, 1, 5, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 11 x 4 x 113 x 1 x 5 x 27 = 161092800
Therefore, the lowest common multiple of 704,678,330,400,810 is 161092800.
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 678 x 330 x 400 x 810 = 51034199040000
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
678 : 1, 2, 3, 6, 113, 226, 339, 678
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 704,678,330,400,810, is 2.
Now, the common factors can be found like this.
704:2x 2x 2x 2x 2x 2x 11
678:2x 3x 113
330:2x 3x 5x 11
400:2x 2x 2x 2x 5x 5
810:2x 3x 3x 3x 3x 5
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 2x 3x 3x 5x 5x 11 = 158400
Therefore, the value for common factors is 158400.
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 = 51034199040000/(2x158400)
LCM = 51034199040000/316800
LCM = 161092800
Thus, we can understand that the LCM of 704,678,330,400,810 is 161092800.
