The LCM of 726,783,990,829 is 785419470.
Find LCM of 726,783,990,829 with Prime Factorization
| 2 | 726, 783, 990, 829 |
| 3 | 363, 783, 495, 829 |
| 3 | 121, 261, 165, 829 |
| 11 | 121, 87, 55, 829 |
| 11, 87, 5, 829 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 11 x 87 x 5 x 829 = 785419470
Therefore, the lowest common multiple of 726,783,990,829 is 785419470.
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.
726 x 783 x 990 x 829 = 466539165180
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.
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
783 : 1, 3, 9, 27, 29, 87, 261, 783
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
829 : 1, 829
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 726,783,990,829, is 1.
Now, the common factors can be found like this.
726:2x 3x 11x 11
783:3x 3x 3x 29
990:2x 3x 3x 5x 11
829:829
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 11 = 594
Therefore, the value for common factors is 594.
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 = 466539165180/(1x594)
LCM = 466539165180/594
LCM = 785419470
Thus, we can understand that the LCM of 726,783,990,829 is 785419470.
