Given numbers are 827,913,209,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 827,913,209,691 is 9913064579.
Find LCM of 827,913,209,691 with Prime Factorization
| 11 | 827, 913, 209, 691 |
| 827, 83, 19, 691 |
Multiply the prime numbers at the bottom and the left side.
11 x 827 x 83 x 19 x 691 = 9913064579
Therefore, the lowest common multiple of 827,913,209,691 is 9913064579.
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.
827 x 913 x 209 x 691 = 109043710369
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.
827 : 1, 827
913 : 1, 11, 83, 913
209 : 1, 11, 19, 209
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 827,913,209,691, is 1.
Now, the common factors can be found like this.
827:827
913:11x 83
209:11x 19
691:691
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 109043710369/(1x11)
LCM = 109043710369/11
LCM = 9913064579
Thus, we can understand that the LCM of 827,913,209,691 is 9913064579.
