Find LCM of 323,840,768,417,817 with Prime Factorization
| 2 | 323, 840, 768, 417, 817 |
| 2 | 323, 420, 384, 417, 817 |
| 2 | 323, 210, 192, 417, 817 |
| 3 | 323, 105, 96, 417, 817 |
| 19 | 323, 35, 32, 139, 817 |
| 17, 35, 32, 139, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 19 x 17 x 35 x 32 x 139 x 43 = 51893748480
Therefore, the lowest common multiple of 323,840,768,417,817 is 51893748480.
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.
323 x 840 x 768 x 417 x 817 = 70990647920640
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.
323 : 1, 17, 19, 323
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
417 : 1, 3, 139, 417
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 323,840,768,417,817, is 1.
Now, the common factors can be found like this.
323:17x 19
840:2x 2x 2x 3x 5x 7
768:2x 2x 2x 2x 2x 2x 2x 2x 3
417:3x 139
817:19x 43
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 19 = 1368
Therefore, the value for common factors is 1368.
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 = 70990647920640/(1x1368)
LCM = 70990647920640/1368
LCM = 51893748480
Thus, we can understand that the LCM of 323,840,768,417,817 is 51893748480.
