Find LCM of 128,849,257,656,668 with Prime Factorization
| 2 | 128, 849, 257, 656, 668 |
| 2 | 64, 849, 257, 328, 334 |
| 2 | 32, 849, 257, 164, 167 |
| 2 | 16, 849, 257, 82, 167 |
| 8, 849, 257, 41, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 8 x 849 x 257 x 41 x 167 = 191227836288
Therefore, the lowest common multiple of 128,849,257,656,668 is 191227836288.
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.
128 x 849 x 257 x 656 x 668 = 12238581522432
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
849 : 1, 3, 283, 849
257 : 1, 257
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
668 : 1, 2, 4, 167, 334, 668
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,849,257,656,668, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
849:3x 283
257:257
656:2x 2x 2x 2x 41
668:2x 2x 167
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 2 = 64
Therefore, the value for common factors is 64.
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 = 12238581522432/(1x64)
LCM = 12238581522432/64
LCM = 191227836288
Thus, we can understand that the LCM of 128,849,257,656,668 is 191227836288.
