Find LCM of 8,256,561,608 with Prime Factorization
| 2 | 8, 256, 561, 608 |
| 2 | 4, 128, 561, 304 |
| 2 | 2, 64, 561, 152 |
| 2 | 1, 32, 561, 76 |
| 2 | 1, 16, 561, 38 |
| 1, 8, 561, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 1 x 8 x 561 x 19 = 2728704
Therefore, the lowest common multiple of 8,256,561,608 is 2728704.
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.
8 x 256 x 561 x 608 = 698548224
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.
8 : 1, 2, 4, 8
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
561 : 1, 3, 11, 17, 33, 51, 187, 561
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8,256,561,608, is 1.
Now, the common factors can be found like this.
8:2x 2x 2
256:2x 2x 2x 2x 2x 2x 2x 2
561:3x 11x 17
608:2x 2x 2x 2x 2x 19
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 2x 2x 2 = 256
Therefore, the value for common factors is 256.
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 = 698548224/(1x256)
LCM = 698548224/256
LCM = 2728704
Thus, we can understand that the LCM of 8,256,561,608 is 2728704.
