Given numbers are 509,921,115,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 509,921,115,561 is 10081307445.
Find LCM of 509,921,115,561 with Prime Factorization
| 3 | 509, 921, 115, 561 |
| 509, 307, 115, 187 |
Multiply the prime numbers at the bottom and the left side.
3 x 509 x 307 x 115 x 187 = 10081307445
Therefore, the lowest common multiple of 509,921,115,561 is 10081307445.
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.
509 x 921 x 115 x 561 = 30243922335
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.
509 : 1, 509
921 : 1, 3, 307, 921
115 : 1, 5, 23, 115
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 509,921,115,561, is 1.
Now, the common factors can be found like this.
509:509
921:3x 307
115:5x 23
561:3x 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.
3 = 3
Therefore, the value for common factors is 3.
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 = 30243922335/(1x3)
LCM = 30243922335/3
LCM = 10081307445
Thus, we can understand that the LCM of 509,921,115,561 is 10081307445.
