Find LCM of 128,487,638,252,112 with Prime Factorization
| 2 | 128, 487, 638, 252, 112 |
| 2 | 64, 487, 319, 126, 56 |
| 2 | 32, 487, 319, 63, 28 |
| 2 | 16, 487, 319, 63, 14 |
| 7 | 8, 487, 319, 63, 7 |
| 8, 487, 319, 9, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 8 x 487 x 319 x 9 x 1 = 1252766592
Therefore, the lowest common multiple of 128,487,638,252,112 is 1252766592.
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 487 x 638 x 252 x 112 = 1122478866432
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
487 : 1, 487
638 : 1, 2, 11, 22, 29, 58, 319, 638
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,487,638,252,112, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
487:487
638:2x 11x 29
252:2x 2x 3x 3x 7
112:2x 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 2x 2x 2x 2x 7 = 896
Therefore, the value for common factors is 896.
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 = 1122478866432/(1x896)
LCM = 1122478866432/896
LCM = 1252766592
Thus, we can understand that the LCM of 128,487,638,252,112 is 1252766592.
