Given numbers are 268,405,389,777
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 268,405,389,777 is 10935513540.
Find LCM of 268,405,389,777 with Prime Factorization
| 3 | 268, 405, 389, 777 |
| 268, 135, 389, 259 |
Multiply the prime numbers at the bottom and the left side.
3 x 268 x 135 x 389 x 259 = 10935513540
Therefore, the lowest common multiple of 268,405,389,777 is 10935513540.
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.
268 x 405 x 389 x 777 = 32806540620
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.
268 : 1, 2, 4, 67, 134, 268
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
389 : 1, 389
777 : 1, 3, 7, 21, 37, 111, 259, 777
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 268,405,389,777, is 1.
Now, the common factors can be found like this.
268:2x 2x 67
405:3x 3x 3x 3x 5
389:389
777:3x 7x 37
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 = 32806540620/(1x3)
LCM = 32806540620/3
LCM = 10935513540
Thus, we can understand that the LCM of 268,405,389,777 is 10935513540.
