The LCM of 726,858,858,981 is 3086226.
Find LCM of 726,858,858,981 with Prime Factorization
| 2 | 726, 858, 858, 981 |
| 3 | 363, 429, 429, 981 |
| 11 | 121, 143, 143, 327 |
| 13 | 11, 13, 13, 327 |
| 11, 1, 1, 327 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 11 x 1 x 1 x 327 = 3086226
Therefore, the lowest common multiple of 726,858,858,981 is 3086226.
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 858 x 858 x 981 = 524300417784
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
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
981 : 1, 3, 9, 109, 327, 981
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 726,858,858,981, is 3.
Now, the common factors can be found like this.
726:2x 3x 11x 11
858:2x 3x 11x 13
858:2x 3x 11x 13
981:3x 3x 109
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 11x 11x 13 = 56628
Therefore, the value for common factors is 56628.
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 = 524300417784/(3x56628)
LCM = 524300417784/169884
LCM = 3086226
Thus, we can understand that the LCM of 726,858,858,981 is 3086226.
