Given numbers are 800,962,218,715,287
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 800,962,218,715,287 is 132414682400.
Find LCM of 800,962,218,715,287 with Prime Factorization
| 2 | 800, 962, 218, 715, 287 |
| 5 | 400, 481, 109, 715, 287 |
| 13 | 80, 481, 109, 143, 287 |
| 80, 37, 109, 11, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 80 x 37 x 109 x 11 x 287 = 132414682400
Therefore, the lowest common multiple of 800,962,218,715,287 is 132414682400.
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.
800 x 962 x 218 x 715 x 287 = 34427817424000
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.
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
962 : 1, 2, 13, 26, 37, 74, 481, 962
218 : 1, 2, 109, 218
715 : 1, 5, 11, 13, 55, 65, 143, 715
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 800,962,218,715,287, is 1.
Now, the common factors can be found like this.
800:2x 2x 2x 2x 2x 5x 5
962:2x 13x 37
218:2x 109
715:5x 11x 13
287:7x 41
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 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 34427817424000/(1x260)
LCM = 34427817424000/260
LCM = 132414682400
Thus, we can understand that the LCM of 800,962,218,715,287 is 132414682400.
