The LCM of 387,860,629,408 is 9736920.
Find LCM of 387,860,629,408 with Prime Factorization
| 2 | 387, 860, 629, 408 |
| 2 | 387, 430, 629, 204 |
| 3 | 387, 215, 629, 102 |
| 17 | 129, 215, 629, 34 |
| 43 | 129, 215, 37, 2 |
| 3, 5, 37, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 43 x 3 x 5 x 37 x 2 = 9736920
Therefore, the lowest common multiple of 387,860,629,408 is 9736920.
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.
387 x 860 x 629 x 408 = 85412262240
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.
387 : 1, 3, 9, 43, 129, 387
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
629 : 1, 17, 37, 629
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,860,629,408, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
860:2x 2x 5x 43
629:17x 37
408:2x 2x 2x 3x 17
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 17x 43 = 8772
Therefore, the value for common factors is 8772.
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 = 85412262240/(1x8772)
LCM = 85412262240/8772
LCM = 9736920
Thus, we can understand that the LCM of 387,860,629,408 is 9736920.
