Given numbers are 561,935,979,979
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,935,979,979 is 249645.
Find LCM of 561,935,979,979 with Prime Factorization
| 11 | 561, 935, 979, 979 |
| 17 | 51, 85, 89, 89 |
| 89 | 3, 5, 89, 89 |
| 3, 5, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 89 x 3 x 5 x 1 x 1 = 249645
Therefore, the lowest common multiple of 561,935,979,979 is 249645.
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 935 x 979 x 979 = 502735849935
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
935 : 1, 5, 11, 17, 55, 85, 187, 935
979 : 1, 11, 89, 979
979 : 1, 11, 89, 979
11 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,935,979,979, is 11.
Now, the common factors can be found like this.
561:3x 11x 17
935:5x 11x 17
979:11x 89
979:11x 89
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 89 = 183073
Therefore, the value for common factors is 183073.
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 = 502735849935/(11x183073)
LCM = 502735849935/2013803
LCM = 249645
Thus, we can understand that the LCM of 561,935,979,979 is 249645.
