The LCM of 286,783,891,774 is 28888002.
Find LCM of 286,783,891,774 with Prime Factorization
| 2 | 286, 783, 891, 774 |
| 3 | 143, 783, 891, 387 |
| 3 | 143, 261, 297, 129 |
| 3 | 143, 87, 99, 43 |
| 11 | 143, 29, 33, 43 |
| 13, 29, 3, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 11 x 13 x 29 x 3 x 43 = 28888002
Therefore, the lowest common multiple of 286,783,891,774 is 28888002.
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.
286 x 783 x 891 x 774 = 154435258692
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.
286 : 1, 2, 11, 13, 22, 26, 143, 286
783 : 1, 3, 9, 27, 29, 87, 261, 783
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
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 286,783,891,774, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
783:3x 3x 3x 29
891:3x 3x 3x 3x 11
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 3x 3x 3x 3x 3x 11 = 5346
Therefore, the value for common factors is 5346.
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 = 154435258692/(1x5346)
LCM = 154435258692/5346
LCM = 28888002
Thus, we can understand that the LCM of 286,783,891,774 is 28888002.
