The LCM of 256,885,935,680 is 42366720.
Find LCM of 256,885,935,680 with Prime Factorization
| 2 | 256, 885, 935, 680 |
| 2 | 128, 885, 935, 340 |
| 2 | 64, 885, 935, 170 |
| 5 | 32, 885, 935, 85 |
| 17 | 32, 177, 187, 17 |
| 32, 177, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 17 x 32 x 177 x 11 x 1 = 42366720
Therefore, the lowest common multiple of 256,885,935,680 is 42366720.
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.
256 x 885 x 935 x 680 = 144046848000
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.
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
885 : 1, 3, 5, 15, 59, 177, 295, 885
935 : 1, 5, 11, 17, 55, 85, 187, 935
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,885,935,680, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
885:3x 5x 59
935:5x 11x 17
680:2x 2x 2x 5x 17
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 5x 5x 17 = 3400
Therefore, the value for common factors is 3400.
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 = 144046848000/(1x3400)
LCM = 144046848000/3400
LCM = 42366720
Thus, we can understand that the LCM of 256,885,935,680 is 42366720.
