Find LCM of 861,832,715,912,846 with Prime Factorization
| 2 | 861, 832, 715, 912, 846 |
| 2 | 861, 416, 715, 456, 423 |
| 2 | 861, 208, 715, 228, 423 |
| 2 | 861, 104, 715, 114, 423 |
| 3 | 861, 52, 715, 57, 423 |
| 13 | 287, 52, 715, 19, 141 |
| 287, 4, 55, 19, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 13 x 287 x 4 x 55 x 19 x 141 = 105550885440
Therefore, the lowest common multiple of 861,832,715,912,846 is 105550885440.
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 832 x 715 x 912 x 846 = 395182515087360
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
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
715 : 1, 5, 11, 13, 55, 65, 143, 715
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,832,715,912,846, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
832:2x 2x 2x 2x 2x 2x 13
715:5x 11x 13
912:2x 2x 2x 2x 3x 19
846:2x 3x 3x 47
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 2x 2x 2x 3x 3x 13 = 3744
Therefore, the value for common factors is 3744.
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 = 395182515087360/(1x3744)
LCM = 395182515087360/3744
LCM = 105550885440
Thus, we can understand that the LCM of 861,832,715,912,846 is 105550885440.
