The LCM of 843,408,384,872 is 199946112.
Find LCM of 843,408,384,872 with Prime Factorization
| 2 | 843, 408, 384, 872 |
| 2 | 843, 204, 192, 436 |
| 2 | 843, 102, 96, 218 |
| 3 | 843, 51, 48, 109 |
| 281, 17, 16, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 281 x 17 x 16 x 109 = 199946112
Therefore, the lowest common multiple of 843,408,384,872 is 199946112.
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.
843 x 408 x 384 x 872 = 115168960512
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.
843 : 1, 3, 281, 843
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
872 : 1, 2, 4, 8, 109, 218, 436, 872
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,408,384,872, is 1.
Now, the common factors can be found like this.
843:3x 281
408:2x 2x 2x 3x 17
384:2x 2x 2x 2x 2x 2x 2x 3
872:2x 2x 2x 109
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 2x 3x 3 = 576
Therefore, the value for common factors is 576.
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 = 115168960512/(1x576)
LCM = 115168960512/576
LCM = 199946112
Thus, we can understand that the LCM of 843,408,384,872 is 199946112.
