Find LCM of 723,784,647,489,896 with Prime Factorization
| 2 | 723, 784, 647, 489, 896 |
| 2 | 723, 392, 647, 489, 448 |
| 2 | 723, 196, 647, 489, 224 |
| 2 | 723, 98, 647, 489, 112 |
| 3 | 723, 49, 647, 489, 56 |
| 7 | 241, 49, 647, 163, 56 |
| 241, 7, 647, 163, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 241 x 7 x 647 x 163 x 8 = 478229356416
Therefore, the lowest common multiple of 723,784,647,489,896 is 478229356416.
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.
723 x 784 x 647 x 489 x 896 = 160685063755776
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.
723 : 1, 3, 241, 723
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
647 : 1, 647
489 : 1, 3, 163, 489
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,784,647,489,896, is 1.
Now, the common factors can be found like this.
723:3x 241
784:2x 2x 2x 2x 7x 7
647:647
489:3x 163
896:2x 2x 2x 2x 2x 2x 2x 7
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 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 160685063755776/(1x336)
LCM = 160685063755776/336
LCM = 478229356416
Thus, we can understand that the LCM of 723,784,647,489,896 is 478229356416.
