Given numbers are 666,993,993,606,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 666,993,993,606,909 is 22265046.
Find LCM of 666,993,993,606,909 with Prime Factorization
| 2 | 666, 993, 993, 606, 909 |
| 3 | 333, 993, 993, 303, 909 |
| 3 | 111, 331, 331, 101, 303 |
| 101 | 37, 331, 331, 101, 101 |
| 331 | 37, 331, 331, 1, 1 |
| 37, 1, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 101 x 331 x 37 x 1 x 1 x 1 x 1 = 22265046
Therefore, the lowest common multiple of 666,993,993,606,909 is 22265046.
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.
666 x 993 x 993 x 606 x 909 = 361750577873436
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.
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
993 : 1, 3, 331, 993
993 : 1, 3, 331, 993
606 : 1, 2, 3, 6, 101, 202, 303, 606
909 : 1, 3, 9, 101, 303, 909
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 666,993,993,606,909, is 3.
Now, the common factors can be found like this.
666:2x 3x 3x 37
993:3x 331
993:3x 331
606:2x 3x 101
909:3x 3x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 101x 331 = 5415822
Therefore, the value for common factors is 5415822.
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 = 361750577873436/(3x5415822)
LCM = 361750577873436/16247466
LCM = 22265046
Thus, we can understand that the LCM of 666,993,993,606,909 is 22265046.
