Find LCM of 855,440,891,969 with Prime Factorization
| 3 | 855, 440, 891, 969 |
| 3 | 285, 440, 297, 323 |
| 5 | 95, 440, 99, 323 |
| 11 | 19, 88, 99, 323 |
| 19 | 19, 8, 9, 323 |
| 1, 8, 9, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 11 x 19 x 1 x 8 x 9 x 17 = 11511720
Therefore, the lowest common multiple of 855,440,891,969 is 11511720.
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 440 x 891 x 969 = 324803179800
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
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,440,891,969, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
440:2x 2x 2x 5x 11
891:3x 3x 3x 3x 11
969:3x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 11x 19 = 28215
Therefore, the value for common factors is 28215.
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 = 324803179800/(1x28215)
LCM = 324803179800/28215
LCM = 11511720
Thus, we can understand that the LCM of 855,440,891,969 is 11511720.
