Find LCM of 418,861,892,209,864 with Prime Factorization
| 2 | 418, 861, 892, 209, 864 |
| 2 | 209, 861, 446, 209, 432 |
| 3 | 209, 861, 223, 209, 216 |
| 11 | 209, 287, 223, 209, 72 |
| 19 | 19, 287, 223, 19, 72 |
| 1, 287, 223, 1, 72 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 19 x 1 x 287 x 223 x 1 x 72 = 11557044576
Therefore, the lowest common multiple of 418,861,892,209,864 is 11557044576.
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.
418 x 861 x 892 x 209 x 864 = 57970135593216
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
861 : 1, 3, 7, 21, 41, 123, 287, 861
892 : 1, 2, 4, 223, 446, 892
209 : 1, 11, 19, 209
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,861,892,209,864, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
861:3x 7x 41
892:2x 2x 223
209:11x 19
864:2x 2x 2x 2x 2x 3x 3x 3
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 3x 11x 19 = 5016
Therefore, the value for common factors is 5016.
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 = 57970135593216/(1x5016)
LCM = 57970135593216/5016
LCM = 11557044576
Thus, we can understand that the LCM of 418,861,892,209,864 is 11557044576.
