Given numbers are 788,605,575,864,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,605,575,864,731 is 8656663989600.
Find LCM of 788,605,575,864,731 with Prime Factorization
| 2 | 788, 605, 575, 864, 731 |
| 2 | 394, 605, 575, 432, 731 |
| 5 | 197, 605, 575, 216, 731 |
| 197, 121, 115, 216, 731 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 197 x 121 x 115 x 216 x 731 = 8656663989600
Therefore, the lowest common multiple of 788,605,575,864,731 is 8656663989600.
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.
788 x 605 x 575 x 864 x 731 = 173133279792000
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.
788 : 1, 2, 4, 197, 394, 788
605 : 1, 5, 11, 55, 121, 605
575 : 1, 5, 23, 25, 115, 575
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
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,605,575,864,731, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
605:5x 11x 11
575:5x 5x 23
864:2x 2x 2x 2x 2x 3x 3x 3
731:17x 43
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 5 = 20
Therefore, the value for common factors is 20.
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 = 173133279792000/(1x20)
LCM = 173133279792000/20
LCM = 8656663989600
Thus, we can understand that the LCM of 788,605,575,864,731 is 8656663989600.
