Find LCM of 216,489,121,640,783 with Prime Factorization
| 2 | 216, 489, 121, 640, 783 |
| 2 | 108, 489, 121, 320, 783 |
| 2 | 54, 489, 121, 160, 783 |
| 3 | 27, 489, 121, 80, 783 |
| 3 | 9, 163, 121, 80, 261 |
| 3 | 3, 163, 121, 80, 87 |
| 1, 163, 121, 80, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 1 x 163 x 121 x 80 x 29 = 9883589760
Therefore, the lowest common multiple of 216,489,121,640,783 is 9883589760.
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.
216 x 489 x 121 x 640 x 783 = 6404566164480
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.
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
489 : 1, 3, 163, 489
121 : 1, 11, 121
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
783 : 1, 3, 9, 27, 29, 87, 261, 783
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,489,121,640,783, is 1.
Now, the common factors can be found like this.
216:2x 2x 2x 3x 3x 3
489:3x 163
121:11x 11
640:2x 2x 2x 2x 2x 2x 2x 5
783:3x 3x 3x 29
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 3x 3 = 648
Therefore, the value for common factors is 648.
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 = 6404566164480/(1x648)
LCM = 6404566164480/648
LCM = 9883589760
Thus, we can understand that the LCM of 216,489,121,640,783 is 9883589760.
