Given numbers are 784,796,806,416
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,796,806,416 is 125748896.
Find LCM of 784,796,806,416 with Prime Factorization
| 2 | 784, 796, 806, 416 |
| 2 | 392, 398, 403, 208 |
| 2 | 196, 199, 403, 104 |
| 2 | 98, 199, 403, 52 |
| 13 | 49, 199, 403, 26 |
| 49, 199, 31, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 13 x 49 x 199 x 31 x 2 = 125748896
Therefore, the lowest common multiple of 784,796,806,416 is 125748896.
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 796 x 806 x 416 = 209246162944
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
796 : 1, 2, 4, 199, 398, 796
806 : 1, 2, 13, 26, 31, 62, 403, 806
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,796,806,416, is 2.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
796:2x 2x 199
806:2x 13x 31
416:2x 2x 2x 2x 2x 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 13 = 832
Therefore, the value for common factors is 832.
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 = 209246162944/(2x832)
LCM = 209246162944/1664
LCM = 125748896
Thus, we can understand that the LCM of 784,796,806,416 is 125748896.
