Find LCM of 128,480,918,996,434 with Prime Factorization
| 2 | 128, 480, 918, 996, 434 |
| 2 | 64, 240, 459, 498, 217 |
| 2 | 32, 120, 459, 249, 217 |
| 2 | 16, 60, 459, 249, 217 |
| 2 | 8, 30, 459, 249, 217 |
| 3 | 4, 15, 459, 249, 217 |
| 4, 5, 153, 83, 217 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 4 x 5 x 153 x 83 x 217 = 5290911360
Therefore, the lowest common multiple of 128,480,918,996,434 is 5290911360.
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 480 x 918 x 996 x 434 = 24380519546880
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
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
434 : 1, 2, 7, 14, 31, 62, 217, 434
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,480,918,996,434, is 2.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
480:2x 2x 2x 2x 2x 3x 5
918:2x 3x 3x 3x 17
996:2x 2x 3x 83
434:2x 7x 31
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 2x 3x 3 = 2304
Therefore, the value for common factors is 2304.
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 = 24380519546880/(2x2304)
LCM = 24380519546880/4608
LCM = 5290911360
Thus, we can understand that the LCM of 128,480,918,996,434 is 5290911360.
