Given numbers are 904,865,585,809,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 904,865,585,809,405 is 666133738920.
Find LCM of 904,865,585,809,405 with Prime Factorization
| 3 | 904, 865, 585, 809, 405 |
| 3 | 904, 865, 195, 809, 135 |
| 5 | 904, 865, 65, 809, 45 |
| 904, 173, 13, 809, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 904 x 173 x 13 x 809 x 9 = 666133738920
Therefore, the lowest common multiple of 904,865,585,809,405 is 666133738920.
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.
904 x 865 x 585 x 809 x 405 = 149880091257000
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.
904 : 1, 2, 4, 8, 113, 226, 452, 904
865 : 1, 5, 173, 865
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
809 : 1, 809
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,865,585,809,405, is 1.
Now, the common factors can be found like this.
904:2x 2x 2x 113
865:5x 173
585:3x 3x 5x 13
809:809
405:3x 3x 3x 3x 5
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 5 = 225
Therefore, the value for common factors is 225.
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 = 149880091257000/(1x225)
LCM = 149880091257000/225
LCM = 666133738920
Thus, we can understand that the LCM of 904,865,585,809,405 is 666133738920.
