Find LCM of 688,731,885,976,799 with Prime Factorization
| 2 | 688, 731, 885, 976, 799 |
| 2 | 344, 731, 885, 488, 799 |
| 2 | 172, 731, 885, 244, 799 |
| 2 | 86, 731, 885, 122, 799 |
| 17 | 43, 731, 885, 61, 799 |
| 43 | 43, 43, 885, 61, 47 |
| 1, 1, 885, 61, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 17 x 43 x 1 x 1 x 885 x 61 x 47 = 29676202320
Therefore, the lowest common multiple of 688,731,885,976,799 is 29676202320.
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.
688 x 731 x 885 x 976 x 799 = 347092862334720
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
731 : 1, 17, 43, 731
885 : 1, 3, 5, 15, 59, 177, 295, 885
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
799 : 1, 17, 47, 799
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,731,885,976,799, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
731:17x 43
885:3x 5x 59
976:2x 2x 2x 2x 61
799:17x 47
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 17x 43 = 11696
Therefore, the value for common factors is 11696.
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 = 347092862334720/(1x11696)
LCM = 347092862334720/11696
LCM = 29676202320
Thus, we can understand that the LCM of 688,731,885,976,799 is 29676202320.
