Find LCM of 981,489,781,368,104 with Prime Factorization
| 2 | 981, 489, 781, 368, 104 |
| 2 | 981, 489, 781, 184, 52 |
| 2 | 981, 489, 781, 92, 26 |
| 3 | 981, 489, 781, 46, 13 |
| 327, 163, 781, 46, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 327 x 163 x 781 x 46 x 13 = 597446218512
Therefore, the lowest common multiple of 981,489,781,368,104 is 597446218512.
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.
981 x 489 x 781 x 368 x 104 = 14338709244288
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.
981 : 1, 3, 9, 109, 327, 981
489 : 1, 3, 163, 489
781 : 1, 11, 71, 781
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
104 : 1, 2, 4, 8, 13, 26, 52, 104
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,489,781,368,104, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
489:3x 163
781:11x 71
368:2x 2x 2x 2x 23
104:2x 2x 2x 13
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 3 = 24
Therefore, the value for common factors is 24.
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 = 14338709244288/(1x24)
LCM = 14338709244288/24
LCM = 597446218512
Thus, we can understand that the LCM of 981,489,781,368,104 is 597446218512.
