Find LCM of 868,656,857,651,415 with Prime Factorization
| 2 | 868, 656, 857, 651, 415 |
| 2 | 434, 328, 857, 651, 415 |
| 7 | 217, 164, 857, 651, 415 |
| 31 | 31, 164, 857, 93, 415 |
| 1, 164, 857, 3, 415 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 31 x 1 x 164 x 857 x 3 x 415 = 151884601680
Therefore, the lowest common multiple of 868,656,857,651,415 is 151884601680.
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.
868 x 656 x 857 x 651 x 415 = 131835834258240
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
857 : 1, 857
651 : 1, 3, 7, 21, 31, 93, 217, 651
415 : 1, 5, 83, 415
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,656,857,651,415, is 1.
Now, the common factors can be found like this.
868:2x 2x 7x 31
656:2x 2x 2x 2x 41
857:857
651:3x 7x 31
415:5x 83
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 7x 31 = 868
Therefore, the value for common factors is 868.
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 = 131835834258240/(1x868)
LCM = 131835834258240/868
LCM = 151884601680
Thus, we can understand that the LCM of 868,656,857,651,415 is 151884601680.
