Find LCM of 784,105,800,739,808 with Prime Factorization
| 2 | 784, 105, 800, 739, 808 |
| 2 | 392, 105, 400, 739, 404 |
| 2 | 196, 105, 200, 739, 202 |
| 2 | 98, 105, 100, 739, 101 |
| 5 | 49, 105, 50, 739, 101 |
| 7 | 49, 21, 10, 739, 101 |
| 7, 3, 10, 739, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 7 x 7 x 3 x 10 x 739 x 101 = 8777546400
Therefore, the lowest common multiple of 784,105,800,739,808 is 8777546400.
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.
784 x 105 x 800 x 739 x 808 = 39323407872000
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
105 : 1, 3, 5, 7, 15, 21, 35, 105
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
739 : 1, 739
808 : 1, 2, 4, 8, 101, 202, 404, 808
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,105,800,739,808, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
105:3x 5x 7
800:2x 2x 2x 2x 2x 5x 5
739:739
808:2x 2x 2x 101
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 2x 5x 7 = 4480
Therefore, the value for common factors is 4480.
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 = 39323407872000/(1x4480)
LCM = 39323407872000/4480
LCM = 8777546400
Thus, we can understand that the LCM of 784,105,800,739,808 is 8777546400.
