Find LCM of 192,512,687,814 with Prime Factorization
| 2 | 192, 512, 687, 814 |
| 2 | 96, 256, 687, 407 |
| 2 | 48, 128, 687, 407 |
| 2 | 24, 64, 687, 407 |
| 2 | 12, 32, 687, 407 |
| 2 | 6, 16, 687, 407 |
| 3 | 3, 8, 687, 407 |
| 1, 8, 229, 407 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 3 x 1 x 8 x 229 x 407 = 143159808
Therefore, the lowest common multiple of 192,512,687,814 is 143159808.
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.
192 x 512 x 687 x 814 = 54973366272
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.
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
687 : 1, 3, 229, 687
814 : 1, 2, 11, 22, 37, 74, 407, 814
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 192,512,687,814, is 1.
Now, the common factors can be found like this.
192:2x 2x 2x 2x 2x 2x 3
512:2x 2x 2x 2x 2x 2x 2x 2x 2
687:3x 229
814:2x 11x 37
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 2x 3 = 384
Therefore, the value for common factors is 384.
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 = 54973366272/(1x384)
LCM = 54973366272/384
LCM = 143159808
Thus, we can understand that the LCM of 192,512,687,814 is 143159808.
