Find LCM of 388,591,261,686,896 with Prime Factorization
| 2 | 388, 591, 261, 686, 896 |
| 2 | 194, 591, 261, 343, 448 |
| 3 | 97, 591, 261, 343, 224 |
| 7 | 97, 197, 87, 343, 224 |
| 97, 197, 87, 49, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 97 x 197 x 87 x 49 x 32 = 218968960896
Therefore, the lowest common multiple of 388,591,261,686,896 is 218968960896.
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.
388 x 591 x 261 x 686 x 896 = 36786785430528
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.
388 : 1, 2, 4, 97, 194, 388
591 : 1, 3, 197, 591
261 : 1, 3, 9, 29, 87, 261
686 : 1, 2, 7, 14, 49, 98, 343, 686
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,591,261,686,896, is 1.
Now, the common factors can be found like this.
388:2x 2x 97
591:3x 197
261:3x 3x 29
686:2x 7x 7x 7
896:2x 2x 2x 2x 2x 2x 2x 7
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 36786785430528/(1x168)
LCM = 36786785430528/168
LCM = 218968960896
Thus, we can understand that the LCM of 388,591,261,686,896 is 218968960896.
