Find LCM of 855,891,874,396 with Prime Factorization
| 2 | 855, 891, 874, 396 |
| 3 | 855, 891, 437, 198 |
| 3 | 285, 297, 437, 66 |
| 11 | 95, 99, 437, 22 |
| 19 | 95, 9, 437, 2 |
| 5, 9, 23, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 19 x 5 x 9 x 23 x 2 = 7787340
Therefore, the lowest common multiple of 855,891,874,396 is 7787340.
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.
855 x 891 x 874 x 396 = 263663757720
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
874 : 1, 2, 19, 23, 38, 46, 437, 874
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,891,874,396, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
891:3x 3x 3x 3x 11
874:2x 19x 23
396:2x 2x 3x 3x 11
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 11x 19 = 33858
Therefore, the value for common factors is 33858.
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 = 263663757720/(1x33858)
LCM = 263663757720/33858
LCM = 7787340
Thus, we can understand that the LCM of 855,891,874,396 is 7787340.
