Given numbers are 684,906,981,802,811
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,906,981,802,811 is 3661211128716.
Find LCM of 684,906,981,802,811 with Prime Factorization
| 2 | 684, 906, 981, 802, 811 |
| 3 | 342, 453, 981, 401, 811 |
| 3 | 114, 151, 327, 401, 811 |
| 38, 151, 109, 401, 811 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 38 x 151 x 109 x 401 x 811 = 3661211128716
Therefore, the lowest common multiple of 684,906,981,802,811 is 3661211128716.
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.
684 x 906 x 981 x 802 x 811 = 395410801901328
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
906 : 1, 2, 3, 6, 151, 302, 453, 906
981 : 1, 3, 9, 109, 327, 981
802 : 1, 2, 401, 802
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,906,981,802,811, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
906:2x 3x 151
981:3x 3x 109
802:2x 401
811:811
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 395410801901328/(1x108)
LCM = 395410801901328/108
LCM = 3661211128716
Thus, we can understand that the LCM of 684,906,981,802,811 is 3661211128716.
