Find LCM of 780,806,895,159,385 with Prime Factorization
| 2 | 780, 806, 895, 159, 385 |
| 3 | 390, 403, 895, 159, 385 |
| 5 | 130, 403, 895, 53, 385 |
| 13 | 26, 403, 179, 53, 77 |
| 2, 31, 179, 53, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 2 x 31 x 179 x 53 x 77 = 17663465820
Therefore, the lowest common multiple of 780,806,895,159,385 is 17663465820.
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.
780 x 806 x 895 x 159 x 385 = 34443758349000
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.
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
806 : 1, 2, 13, 26, 31, 62, 403, 806
895 : 1, 5, 179, 895
159 : 1, 3, 53, 159
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,806,895,159,385, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
806:2x 13x 31
895:5x 179
159:3x 53
385:5x 7x 11
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 5x 13 = 1950
Therefore, the value for common factors is 1950.
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 = 34443758349000/(1x1950)
LCM = 34443758349000/1950
LCM = 17663465820
Thus, we can understand that the LCM of 780,806,895,159,385 is 17663465820.
