Given numbers are 664,913,538,441
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 664,913,538,441 is 866466216.
Find LCM of 664,913,538,441 with Prime Factorization
| 2 | 664, 913, 538, 441 |
| 83 | 332, 913, 269, 441 |
| 4, 11, 269, 441 |
Multiply the prime numbers at the bottom and the left side.
2 x 83 x 4 x 11 x 269 x 441 = 866466216
Therefore, the lowest common multiple of 664,913,538,441 is 866466216.
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.
664 x 913 x 538 x 441 = 143833391856
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.
664 : 1, 2, 4, 8, 83, 166, 332, 664
913 : 1, 11, 83, 913
538 : 1, 2, 269, 538
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,913,538,441, is 1.
Now, the common factors can be found like this.
664:2x 2x 2x 83
913:11x 83
538:2x 269
441:3x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 83 = 166
Therefore, the value for common factors is 166.
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 = 143833391856/(1x166)
LCM = 143833391856/166
LCM = 866466216
Thus, we can understand that the LCM of 664,913,538,441 is 866466216.
