Find LCM of 784,655,704,663,728 with Prime Factorization
| 2 | 784, 655, 704, 663, 728 |
| 2 | 392, 655, 352, 663, 364 |
| 2 | 196, 655, 176, 663, 182 |
| 2 | 98, 655, 88, 663, 91 |
| 7 | 49, 655, 44, 663, 91 |
| 13 | 7, 655, 44, 663, 13 |
| 7, 655, 44, 51, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 13 x 7 x 655 x 44 x 51 x 1 = 14980405440
Therefore, the lowest common multiple of 784,655,704,663,728 is 14980405440.
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 655 x 704 x 663 x 728 = 174491762565120
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
655 : 1, 5, 131, 655
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
663 : 1, 3, 13, 17, 39, 51, 221, 663
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,655,704,663,728, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
655:5x 131
704:2x 2x 2x 2x 2x 2x 11
663:3x 13x 17
728:2x 2x 2x 7x 13
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 7x 13 = 11648
Therefore, the value for common factors is 11648.
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 = 174491762565120/(1x11648)
LCM = 174491762565120/11648
LCM = 14980405440
Thus, we can understand that the LCM of 784,655,704,663,728 is 14980405440.
