Given numbers are 816,906,638,783,955
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,906,638,783,955 is 337834244880.
Find LCM of 816,906,638,783,955 with Prime Factorization
| 2 | 816, 906, 638, 783, 955 |
| 3 | 408, 453, 319, 783, 955 |
| 29 | 136, 151, 319, 261, 955 |
| 136, 151, 11, 9, 955 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 136 x 151 x 11 x 9 x 955 = 337834244880
Therefore, the lowest common multiple of 816,906,638,783,955 is 337834244880.
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.
816 x 906 x 638 x 783 x 955 = 352698951654720
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
906 : 1, 2, 3, 6, 151, 302, 453, 906
638 : 1, 2, 11, 22, 29, 58, 319, 638
783 : 1, 3, 9, 27, 29, 87, 261, 783
955 : 1, 5, 191, 955
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,906,638,783,955, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
906:2x 3x 151
638:2x 11x 29
783:3x 3x 3x 29
955:5x 191
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 29 = 1044
Therefore, the value for common factors is 1044.
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 = 352698951654720/(1x1044)
LCM = 352698951654720/1044
LCM = 337834244880
Thus, we can understand that the LCM of 816,906,638,783,955 is 337834244880.
