Find LCM of 416,800,819,805 with Prime Factorization
| 2 | 416, 800, 819, 805 |
| 2 | 208, 400, 819, 805 |
| 2 | 104, 200, 819, 805 |
| 2 | 52, 100, 819, 805 |
| 2 | 26, 50, 819, 805 |
| 5 | 13, 25, 819, 805 |
| 7 | 13, 5, 819, 161 |
| 13 | 13, 5, 117, 23 |
| 1, 5, 9, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 7 x 13 x 1 x 5 x 9 x 23 = 15069600
Therefore, the lowest common multiple of 416,800,819,805 is 15069600.
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.
416 x 800 x 819 x 805 = 219413376000
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.
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 416,800,819,805, is 1.
Now, the common factors can be found like this.
416:2x 2x 2x 2x 2x 13
800:2x 2x 2x 2x 2x 5x 5
819:3x 3x 7x 13
805:5x 7x 23
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 5x 7x 13 = 14560
Therefore, the value for common factors is 14560.
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 = 219413376000/(1x14560)
LCM = 219413376000/14560
LCM = 15069600
Thus, we can understand that the LCM of 416,800,819,805 is 15069600.
