Find LCM of 646,288,934,848,864 with Prime Factorization
| 2 | 646, 288, 934, 848, 864 |
| 2 | 323, 144, 467, 424, 432 |
| 2 | 323, 72, 467, 212, 216 |
| 2 | 323, 36, 467, 106, 108 |
| 2 | 323, 18, 467, 53, 54 |
| 3 | 323, 9, 467, 53, 27 |
| 3 | 323, 3, 467, 53, 9 |
| 323, 1, 467, 53, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 3 x 323 x 1 x 467 x 53 x 3 = 6907311072
Therefore, the lowest common multiple of 646,288,934,848,864 is 6907311072.
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.
646 x 288 x 934 x 848 x 864 = 127315557679104
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
934 : 1, 2, 467, 934
848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,288,934,848,864, is 2.
Now, the common factors can be found like this.
646:2x 17x 19
288:2x 2x 2x 2x 2x 3x 3
934:2x 467
848:2x 2x 2x 2x 53
864:2x 2x 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 2x 2x 2x 2x 2x 2x 2x 3x 3 = 9216
Therefore, the value for common factors is 9216.
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 = 127315557679104/(2x9216)
LCM = 127315557679104/18432
LCM = 6907311072
Thus, we can understand that the LCM of 646,288,934,848,864 is 6907311072.
