Given numbers are 806,845,646,835
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 806,845,646,835 is 2825968990.
Find LCM of 806,845,646,835 with Prime Factorization
| 2 | 806, 845, 646, 835 |
| 5 | 403, 845, 323, 835 |
| 13 | 403, 169, 323, 167 |
| 31, 13, 323, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 31 x 13 x 323 x 167 = 2825968990
Therefore, the lowest common multiple of 806,845,646,835 is 2825968990.
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.
806 x 845 x 646 x 835 = 367375968700
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
845 : 1, 5, 13, 65, 169, 845
646 : 1, 2, 17, 19, 34, 38, 323, 646
835 : 1, 5, 167, 835
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,845,646,835, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
845:5x 13x 13
646:2x 17x 19
835:5x 167
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 367375968700/(1x130)
LCM = 367375968700/130
LCM = 2825968990
Thus, we can understand that the LCM of 806,845,646,835 is 2825968990.
