The LCM of 806,403,839,858,774 is 2878728138.
Find LCM of 806,403,839,858,774 with Prime Factorization
| 2 | 806, 403, 839, 858, 774 |
| 3 | 403, 403, 839, 429, 387 |
| 13 | 403, 403, 839, 143, 129 |
| 31 | 31, 31, 839, 11, 129 |
| 1, 1, 839, 11, 129 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 31 x 1 x 1 x 839 x 11 x 129 = 2878728138
Therefore, the lowest common multiple of 806,403,839,858,774 is 2878728138.
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.
806 x 403 x 839 x 858 x 774 = 180979880579784
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
403 : 1, 13, 31, 403
839 : 1, 839
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,403,839,858,774, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
403:13x 31
839:839
858:2x 3x 11x 13
774:2x 3x 3x 43
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 13x 13x 31 = 62868
Therefore, the value for common factors is 62868.
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 = 180979880579784/(1x62868)
LCM = 180979880579784/62868
LCM = 2878728138
Thus, we can understand that the LCM of 806,403,839,858,774 is 2878728138.
