The LCM of 663,649,517,940,804 is 27099475260.
Find LCM of 663,649,517,940,804 with Prime Factorization
| 2 | 663, 649, 517, 940, 804 |
| 2 | 663, 649, 517, 470, 402 |
| 3 | 663, 649, 517, 235, 201 |
| 11 | 221, 649, 517, 235, 67 |
| 47 | 221, 59, 47, 235, 67 |
| 221, 59, 1, 5, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 47 x 221 x 59 x 1 x 5 x 67 = 27099475260
Therefore, the lowest common multiple of 663,649,517,940,804 is 27099475260.
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.
663 x 649 x 517 x 940 x 804 = 168125144513040
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.
663 : 1, 3, 13, 17, 39, 51, 221, 663
649 : 1, 11, 59, 649
517 : 1, 11, 47, 517
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,649,517,940,804, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
649:11x 59
517:11x 47
940:2x 2x 5x 47
804:2x 2x 3x 67
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 3x 11x 47 = 6204
Therefore, the value for common factors is 6204.
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 = 168125144513040/(1x6204)
LCM = 168125144513040/6204
LCM = 27099475260
Thus, we can understand that the LCM of 663,649,517,940,804 is 27099475260.
