The LCM of 830,758,704,560 is 775100480.
Find LCM of 830,758,704,560 with Prime Factorization
| 2 | 830, 758, 704, 560 |
| 2 | 415, 379, 352, 280 |
| 2 | 415, 379, 176, 140 |
| 2 | 415, 379, 88, 70 |
| 5 | 415, 379, 44, 35 |
| 83, 379, 44, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 83 x 379 x 44 x 7 = 775100480
Therefore, the lowest common multiple of 830,758,704,560 is 775100480.
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.
830 x 758 x 704 x 560 = 248032153600
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.
830 : 1, 2, 5, 10, 83, 166, 415, 830
758 : 1, 2, 379, 758
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,758,704,560, is 2.
Now, the common factors can be found like this.
830:2x 5x 83
758:2x 379
704:2x 2x 2x 2x 2x 2x 11
560:2x 2x 2x 2x 5x 7
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 5 = 160
Therefore, the value for common factors is 160.
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 = 248032153600/(2x160)
LCM = 248032153600/320
LCM = 775100480
Thus, we can understand that the LCM of 830,758,704,560 is 775100480.
