Given numbers are 9,660,780,843
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 9,660,780,843 is 7232940.
Find LCM of 9,660,780,843 with Prime Factorization
| 2 | 9, 660, 780, 843 |
| 2 | 9, 330, 390, 843 |
| 3 | 9, 165, 195, 843 |
| 5 | 3, 55, 65, 281 |
| 3, 11, 13, 281 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 3 x 11 x 13 x 281 = 7232940
Therefore, the lowest common multiple of 9,660,780,843 is 7232940.
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.
9 x 660 x 780 x 843 = 3905787600
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.
9 : 1, 3, 9
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
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
843 : 1, 3, 281, 843
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 9,660,780,843, is 3.
Now, the common factors can be found like this.
9:3x 3
660:2x 2x 3x 5x 11
780:2x 2x 3x 5x 13
843:3x 281
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 3905787600/(3x180)
LCM = 3905787600/540
LCM = 7232940
Thus, we can understand that the LCM of 9,660,780,843 is 7232940.
