Find LCM of 389,478,729,808,648 with Prime Factorization
| 2 | 389, 478, 729, 808, 648 |
| 2 | 389, 239, 729, 404, 324 |
| 2 | 389, 239, 729, 202, 162 |
| 3 | 389, 239, 729, 101, 81 |
| 3 | 389, 239, 243, 101, 27 |

| 3 | 389, 239, 27, 101, 3 |
| 389, 239, 9, 101, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 3 x 389 x 239 x 9 x 101 x 1 = 54762894072
Therefore, the lowest common multiple of 389,478,729,808,648 is 54762894072.
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.
389 x 478 x 729 x 808 x 648 = 70972710717312
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.
389 : 1, 389
478 : 1, 2, 239, 478
729 : 1, 3, 9, 27, 81, 243, 729
808 : 1, 2, 4, 8, 101, 202, 404, 808
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,478,729,808,648, is 1.
Now, the common factors can be found like this.
389:389
478:2x 239
729:3x 3x 3x 3x 3x 3
808:2x 2x 2x 101
648:2x 2x 2x 3x 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 3x 3x 3x 3 = 1296
Therefore, the value for common factors is 1296.
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 = 70972710717312/(1x1296)
LCM = 70972710717312/1296
LCM = 54762894072
Thus, we can understand that the LCM of 389,478,729,808,648 is 54762894072.
