Find LCM of 784,663,493,812 with Prime Factorization
| 2 | 784, 663, 493, 812 |
| 2 | 392, 663, 493, 406 |
| 7 | 196, 663, 493, 203 |
| 17 | 28, 663, 493, 29 |
| 29 | 28, 39, 29, 29 |
| 28, 39, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 17 x 29 x 28 x 39 x 1 x 1 = 15073968
Therefore, the lowest common multiple of 784,663,493,812 is 15073968.
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 663 x 493 x 812 = 208081054272
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
663 : 1, 3, 13, 17, 39, 51, 221, 663
493 : 1, 17, 29, 493
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,663,493,812, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
663:3x 13x 17
493:17x 29
812:2x 2x 7x 29
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 7x 17x 29 = 13804
Therefore, the value for common factors is 13804.
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 = 208081054272/(1x13804)
LCM = 208081054272/13804
LCM = 15073968
Thus, we can understand that the LCM of 784,663,493,812 is 15073968.
