Given numbers are 891,682,286,484
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 891,682,286,484 is 15799212.
Find LCM of 891,682,286,484 with Prime Factorization
| 2 | 891, 682, 286, 484 |
| 11 | 891, 341, 143, 242 |
| 81, 31, 13, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 81 x 31 x 13 x 22 = 15799212
Therefore, the lowest common multiple of 891,682,286,484 is 15799212.
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.
891 x 682 x 286 x 484 = 84115004688
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
682 : 1, 2, 11, 22, 31, 62, 341, 682
286 : 1, 2, 11, 13, 22, 26, 143, 286
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
11 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,682,286,484, is 11.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
682:2x 11x 31
286:2x 11x 13
484:2x 2x 11x 11
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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 84115004688/(11x484)
LCM = 84115004688/5324
LCM = 15799212
Thus, we can understand that the LCM of 891,682,286,484 is 15799212.
