The LCM of 687,629,418,678,296 is 81643591128.
Find LCM of 687,629,418,678,296 with Prime Factorization
| 2 | 687, 629, 418, 678, 296 |
| 3 | 687, 629, 209, 339, 148 |
| 37 | 229, 629, 209, 113, 148 |
| 229, 17, 209, 113, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 37 x 229 x 17 x 209 x 113 x 4 = 81643591128
Therefore, the lowest common multiple of 687,629,418,678,296 is 81643591128.
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.
687 x 629 x 418 x 678 x 296 = 36249754460832
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.
687 : 1, 3, 229, 687
629 : 1, 17, 37, 629
418 : 1, 2, 11, 19, 22, 38, 209, 418
678 : 1, 2, 3, 6, 113, 226, 339, 678
296 : 1, 2, 4, 8, 37, 74, 148, 296
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,629,418,678,296, is 1.
Now, the common factors can be found like this.
687:3x 229
629:17x 37
418:2x 11x 19
678:2x 3x 113
296:2x 2x 2x 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 3x 37 = 444
Therefore, the value for common factors is 444.
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 = 36249754460832/(1x444)
LCM = 36249754460832/444
LCM = 81643591128
Thus, we can understand that the LCM of 687,629,418,678,296 is 81643591128.
