Find LCM of 861,887,693,868,814 with Prime Factorization
| 2 | 861, 887, 693, 868, 814 |
| 3 | 861, 887, 693, 434, 407 |
| 7 | 287, 887, 231, 434, 407 |
| 11 | 41, 887, 33, 62, 407 |
| 41, 887, 3, 62, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 41 x 887 x 3 x 62 x 37 = 115628294628
Therefore, the lowest common multiple of 861,887,693,868,814 is 115628294628.
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 887 x 693 x 868 x 814 = 373941904826952
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
887 : 1, 887
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
814 : 1, 2, 11, 22, 37, 74, 407, 814
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,887,693,868,814, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
887:887
693:3x 3x 7x 11
868:2x 2x 7x 31
814:2x 11x 37
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 7x 7x 11 = 3234
Therefore, the value for common factors is 3234.
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 = 373941904826952/(1x3234)
LCM = 373941904826952/3234
LCM = 115628294628
Thus, we can understand that the LCM of 861,887,693,868,814 is 115628294628.
