Given numbers are 843,771,557,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,771,557,285 is 11464087665.
Find LCM of 843,771,557,285 with Prime Factorization
| 3 | 843, 771, 557, 285 |
| 281, 257, 557, 95 |
Multiply the prime numbers at the bottom and the left side.
3 x 281 x 257 x 557 x 95 = 11464087665
Therefore, the lowest common multiple of 843,771,557,285 is 11464087665.
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.
843 x 771 x 557 x 285 = 103176788985
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.
843 : 1, 3, 281, 843
771 : 1, 3, 257, 771
557 : 1, 557
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,771,557,285, is 1.
Now, the common factors can be found like this.
843:3x 281
771:3x 257
557:557
285:3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 103176788985/(1x9)
LCM = 103176788985/9
LCM = 11464087665
Thus, we can understand that the LCM of 843,771,557,285 is 11464087665.
