Find LCM of 268,408,836,438,891 with Prime Factorization
| 2 | 268, 408, 836, 438, 891 |
| 2 | 134, 204, 418, 219, 891 |
| 3 | 67, 102, 209, 219, 891 |
| 11 | 67, 34, 209, 73, 297 |
| 67, 34, 19, 73, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 67 x 34 x 19 x 73 x 27 = 11260764504
Therefore, the lowest common multiple of 268,408,836,438,891 is 11260764504.
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.
268 x 408 x 836 x 438 x 891 = 35674101948672
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.
268 : 1, 2, 4, 67, 134, 268
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
438 : 1, 2, 3, 6, 73, 146, 219, 438
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 268,408,836,438,891, is 1.
Now, the common factors can be found like this.
268:2x 2x 67
408:2x 2x 2x 3x 17
836:2x 2x 11x 19
438:2x 3x 73
891:3x 3x 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 2x 2x 2x 2x 3x 3x 11 = 3168
Therefore, the value for common factors is 3168.
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 = 35674101948672/(1x3168)
LCM = 35674101948672/3168
LCM = 11260764504
Thus, we can understand that the LCM of 268,408,836,438,891 is 11260764504.
