Given numbers are 813,408,844,629
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,408,844,629 is 863204376.
Find LCM of 813,408,844,629 with Prime Factorization
| 2 | 813, 408, 844, 629 |
| 2 | 813, 204, 422, 629 |
| 3 | 813, 102, 211, 629 |
| 17 | 271, 34, 211, 629 |
| 271, 2, 211, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 271 x 2 x 211 x 37 = 863204376
Therefore, the lowest common multiple of 813,408,844,629 is 863204376.
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.
813 x 408 x 844 x 629 = 176093692704
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.
813 : 1, 3, 271, 813
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
844 : 1, 2, 4, 211, 422, 844
629 : 1, 17, 37, 629
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,408,844,629, is 1.
Now, the common factors can be found like this.
813:3x 271
408:2x 2x 2x 3x 17
844:2x 2x 211
629:17x 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 17 = 204
Therefore, the value for common factors is 204.
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 = 176093692704/(1x204)
LCM = 176093692704/204
LCM = 863204376
Thus, we can understand that the LCM of 813,408,844,629 is 863204376.
