The LCM of 665,979,385,643,511 is 30558931865.
Find LCM of 665,979,385,643,511 with Prime Factorization
| 5 | 665, 979, 385, 643, 511 |
| 7 | 133, 979, 77, 643, 511 |
| 11 | 19, 979, 11, 643, 73 |
| 19, 89, 1, 643, 73 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 11 x 19 x 89 x 1 x 643 x 73 = 30558931865
Therefore, the lowest common multiple of 665,979,385,643,511 is 30558931865.
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.
665 x 979 x 385 x 643 x 511 = 82356321376175
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
979 : 1, 11, 89, 979
385 : 1, 5, 7, 11, 35, 55, 77, 385
643 : 1, 643
511 : 1, 7, 73, 511
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,979,385,643,511, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
979:11x 89
385:5x 7x 11
643:643
511:7x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 7x 11 = 2695
Therefore, the value for common factors is 2695.
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 = 82356321376175/(1x2695)
LCM = 82356321376175/2695
LCM = 30558931865
Thus, we can understand that the LCM of 665,979,385,643,511 is 30558931865.
