Given numbers are 765,585,263,729
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 765,585,263,729 is 211858335.
Find LCM of 765,585,263,729 with Prime Factorization
| 3 | 765, 585, 263, 729 |
| 3 | 255, 195, 263, 243 |
| 5 | 85, 65, 263, 81 |
| 17, 13, 263, 81 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 17 x 13 x 263 x 81 = 211858335
Therefore, the lowest common multiple of 765,585,263,729 is 211858335.
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.
765 x 585 x 263 x 729 = 85802625675
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
263 : 1, 263
729 : 1, 3, 9, 27, 81, 243, 729
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,585,263,729, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
585:3x 3x 5x 13
263:263
729:3x 3x 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.
3x 3x 3x 3x 5 = 405
Therefore, the value for common factors is 405.
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 = 85802625675/(1x405)
LCM = 85802625675/405
LCM = 211858335
Thus, we can understand that the LCM of 765,585,263,729 is 211858335.
