The LCM of 993,781,485,960,216 is 216652898880.
Find LCM of 993,781,485,960,216 with Prime Factorization
| 2 | 993, 781, 485, 960, 216 |
| 2 | 993, 781, 485, 480, 108 |
| 2 | 993, 781, 485, 240, 54 |
| 3 | 993, 781, 485, 120, 27 |
| 5 | 331, 781, 485, 40, 9 |
| 331, 781, 97, 8, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 331 x 781 x 97 x 8 x 9 = 216652898880
Therefore, the lowest common multiple of 993,781,485,960,216 is 216652898880.
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.
993 x 781 x 485 x 960 x 216 = 77995043596800
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.
993 : 1, 3, 331, 993
781 : 1, 11, 71, 781
485 : 1, 5, 97, 485
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,781,485,960,216, is 1.
Now, the common factors can be found like this.
993:3x 331
781:11x 71
485:5x 97
960:2x 2x 2x 2x 2x 2x 3x 5
216:2x 2x 2x 3x 3x 3
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 3x 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 77995043596800/(1x360)
LCM = 77995043596800/360
LCM = 216652898880
Thus, we can understand that the LCM of 993,781,485,960,216 is 216652898880.
