Find LCM of 858,856,928,284,393 with Prime Factorization
| 2 | 858, 856, 928, 284, 393 |
| 2 | 429, 428, 464, 142, 393 |
| 2 | 429, 214, 232, 71, 393 |
| 3 | 429, 107, 116, 71, 393 |
| 143, 107, 116, 71, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 143 x 107 x 116 x 71 x 131 = 396203849184
Therefore, the lowest common multiple of 858,856,928,284,393 is 396203849184.
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.
858 x 856 x 928 x 284 x 393 = 76071139043328
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
856 : 1, 2, 4, 8, 107, 214, 428, 856
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
284 : 1, 2, 4, 71, 142, 284
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,856,928,284,393, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
856:2x 2x 2x 107
928:2x 2x 2x 2x 2x 29
284:2x 2x 71
393:3x 131
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 3 = 192
Therefore, the value for common factors is 192.
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 = 76071139043328/(1x192)
LCM = 76071139043328/192
LCM = 396203849184
Thus, we can understand that the LCM of 858,856,928,284,393 is 396203849184.
