Given numbers are 861,898,835,400,345
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,898,835,400,345 is 593955339600.
Find LCM of 861,898,835,400,345 with Prime Factorization
| 2 | 861, 898, 835, 400, 345 |
| 3 | 861, 449, 835, 200, 345 |
| 5 | 287, 449, 835, 200, 115 |
| 287, 449, 167, 40, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 287 x 449 x 167 x 40 x 23 = 593955339600
Therefore, the lowest common multiple of 861,898,835,400,345 is 593955339600.
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.
861 x 898 x 835 x 400 x 345 = 89093300940000
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
898 : 1, 2, 449, 898
835 : 1, 5, 167, 835
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,898,835,400,345, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
898:2x 449
835:5x 167
400:2x 2x 2x 2x 5x 5
345:3x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 89093300940000/(1x150)
LCM = 89093300940000/150
LCM = 593955339600
Thus, we can understand that the LCM of 861,898,835,400,345 is 593955339600.
