The LCM of 104,685,717,642,455 is 38258230920.
Find LCM of 104,685,717,642,455 with Prime Factorization
| 2 | 104, 685, 717, 642, 455 |
| 3 | 52, 685, 717, 321, 455 |
| 5 | 52, 685, 239, 107, 455 |
| 13 | 52, 137, 239, 107, 91 |
| 4, 137, 239, 107, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 4 x 137 x 239 x 107 x 7 = 38258230920
Therefore, the lowest common multiple of 104,685,717,642,455 is 38258230920.
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.
104 x 685 x 717 x 642 x 455 = 14920710058800
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.
104 : 1, 2, 4, 8, 13, 26, 52, 104
685 : 1, 5, 137, 685
717 : 1, 3, 239, 717
642 : 1, 2, 3, 6, 107, 214, 321, 642
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 104,685,717,642,455, is 1.
Now, the common factors can be found like this.
104:2x 2x 2x 13
685:5x 137
717:3x 239
642:2x 3x 107
455:5x 7x 13
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 5x 13 = 390
Therefore, the value for common factors is 390.
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 = 14920710058800/(1x390)
LCM = 14920710058800/390
LCM = 38258230920
Thus, we can understand that the LCM of 104,685,717,642,455 is 38258230920.
