Given numbers are 396,968,780,724
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,968,780,724 is 102496680.
Find LCM of 396,968,780,724 with Prime Factorization
| 2 | 396, 968, 780, 724 |
| 2 | 198, 484, 390, 362 |
| 3 | 99, 242, 195, 181 |
| 11 | 33, 242, 65, 181 |
| 3, 22, 65, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 3 x 22 x 65 x 181 = 102496680
Therefore, the lowest common multiple of 396,968,780,724 is 102496680.
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.
396 x 968 x 780 x 724 = 216472988160
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
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
724 : 1, 2, 4, 181, 362, 724
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,968,780,724, is 4.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
968:2x 2x 2x 11x 11
780:2x 2x 3x 5x 13
724:2x 2x 181
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 3x 11 = 528
Therefore, the value for common factors is 528.
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 = 216472988160/(4x528)
LCM = 216472988160/2112
LCM = 102496680
Thus, we can understand that the LCM of 396,968,780,724 is 102496680.
