Given numbers are 259,780,783,747,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 259,780,783,747,891 is 144419855580.
Find LCM of 259,780,783,747,891 with Prime Factorization
| 3 | 259, 780, 783, 747, 891 |
| 3 | 259, 260, 261, 249, 297 |
| 3 | 259, 260, 87, 83, 99 |
| 259, 260, 29, 83, 33 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 259 x 260 x 29 x 83 x 33 = 144419855580
Therefore, the lowest common multiple of 259,780,783,747,891 is 144419855580.
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.
259 x 780 x 783 x 747 x 891 = 105282074717820
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.
259 : 1, 7, 37, 259
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
783 : 1, 3, 9, 27, 29, 87, 261, 783
747 : 1, 3, 9, 83, 249, 747
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 259,780,783,747,891, is 1.
Now, the common factors can be found like this.
259:7x 37
780:2x 2x 3x 5x 13
783:3x 3x 3x 29
747:3x 3x 83
891:3x 3x 3x 3x 11
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 3x 3 = 729
Therefore, the value for common factors is 729.
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 = 105282074717820/(1x729)
LCM = 105282074717820/729
LCM = 144419855580
Thus, we can understand that the LCM of 259,780,783,747,891 is 144419855580.
