Given numbers are 561,405,935,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,405,935,210 is 1060290.
Find LCM of 561,405,935,210 with Prime Factorization
| 3 | 561, 405, 935, 210 |
| 5 | 187, 135, 935, 70 |
| 11 | 187, 27, 187, 14 |
| 17 | 17, 27, 17, 14 |
| 1, 27, 1, 14 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 17 x 1 x 27 x 1 x 14 = 1060290
Therefore, the lowest common multiple of 561,405,935,210 is 1060290.
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.
561 x 405 x 935 x 210 = 44611701750
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
935 : 1, 5, 11, 17, 55, 85, 187, 935
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,405,935,210, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
405:3x 3x 3x 3x 5
935:5x 11x 17
210:2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5x 11x 17 = 42075
Therefore, the value for common factors is 42075.
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 = 44611701750/(1x42075)
LCM = 44611701750/42075
LCM = 1060290
Thus, we can understand that the LCM of 561,405,935,210 is 1060290.
