Given numbers are 731,561,836,187
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,561,836,187 is 1833348.
Find LCM of 731,561,836,187 with Prime Factorization
| 11 | 731, 561, 836, 187 |
| 17 | 731, 51, 76, 17 |
| 43, 3, 76, 1 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 43 x 3 x 76 x 1 = 1833348
Therefore, the lowest common multiple of 731,561,836,187 is 1833348.
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.
731 x 561 x 836 x 187 = 64110346212
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.
731 : 1, 17, 43, 731
561 : 1, 3, 11, 17, 33, 51, 187, 561
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
187 : 1, 11, 17, 187
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,561,836,187, is 1.
Now, the common factors can be found like this.
731:17x 43
561:3x 11x 17
836:2x 2x 11x 19
187:11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11x 17x 17 = 34969
Therefore, the value for common factors is 34969.
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 = 64110346212/(1x34969)
LCM = 64110346212/34969
LCM = 1833348
Thus, we can understand that the LCM of 731,561,836,187 is 1833348.
