Given numbers are 861,258,847,642,914
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,258,847,642,914 is 438113817834.
Find LCM of 861,258,847,642,914 with Prime Factorization
| 2 | 861, 258, 847, 642, 914 |
| 3 | 861, 129, 847, 321, 457 |
| 7 | 287, 43, 847, 107, 457 |
| 41, 43, 121, 107, 457 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 41 x 43 x 121 x 107 x 457 = 438113817834
Therefore, the lowest common multiple of 861,258,847,642,914 is 438113817834.
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 258 x 847 x 642 x 914 = 110404682094168
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
258 : 1, 2, 3, 6, 43, 86, 129, 258
847 : 1, 7, 11, 77, 121, 847
642 : 1, 2, 3, 6, 107, 214, 321, 642
914 : 1, 2, 457, 914
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,258,847,642,914, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
258:2x 3x 43
847:7x 11x 11
642:2x 3x 107
914:2x 457
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 7 = 252
Therefore, the value for common factors is 252.
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 = 110404682094168/(1x252)
LCM = 110404682094168/252
LCM = 438113817834
Thus, we can understand that the LCM of 861,258,847,642,914 is 438113817834.
