Find LCM of 104,715,680,680,729 with Prime Factorization
| 2 | 104, 715, 680, 680, 729 |
| 2 | 52, 715, 340, 340, 729 |
| 2 | 26, 715, 170, 170, 729 |
| 5 | 13, 715, 85, 85, 729 |
| 13 | 13, 143, 17, 17, 729 |
| 17 | 1, 11, 17, 17, 729 |
| 1, 11, 1, 1, 729 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 13 x 17 x 1 x 11 x 1 x 1 x 729 = 70887960
Therefore, the lowest common multiple of 104,715,680,680,729 is 70887960.
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 715 x 680 x 680 x 729 = 25065982656000
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
715 : 1, 5, 11, 13, 55, 65, 143, 715
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
729 : 1, 3, 9, 27, 81, 243, 729
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 104,715,680,680,729, is 1.
Now, the common factors can be found like this.
104:2x 2x 2x 13
715:5x 11x 13
680:2x 2x 2x 5x 17
680:2x 2x 2x 5x 17
729:3x 3x 3x 3x 3x 3
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 5x 5x 13x 17 = 353600
Therefore, the value for common factors is 353600.
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 = 25065982656000/(1x353600)
LCM = 25065982656000/353600
LCM = 70887960
Thus, we can understand that the LCM of 104,715,680,680,729 is 70887960.
