The LCM of 405,412,878,927,788 is 14430553380.
Find LCM of 405,412,878,927,788 with Prime Factorization
| 2 | 405, 412, 878, 927, 788 |
| 2 | 405, 206, 439, 927, 394 |
| 3 | 405, 103, 439, 927, 197 |
| 3 | 135, 103, 439, 309, 197 |
| 103 | 45, 103, 439, 103, 197 |
| 45, 1, 439, 1, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 103 x 45 x 1 x 439 x 1 x 197 = 14430553380
Therefore, the lowest common multiple of 405,412,878,927,788 is 14430553380.
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.
405 x 412 x 878 x 927 x 788 = 107016983866080
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
412 : 1, 2, 4, 103, 206, 412
878 : 1, 2, 439, 878
927 : 1, 3, 9, 103, 309, 927
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,412,878,927,788, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
412:2x 2x 103
878:2x 439
927:3x 3x 103
788:2x 2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3x 103 = 7416
Therefore, the value for common factors is 7416.
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 = 107016983866080/(1x7416)
LCM = 107016983866080/7416
LCM = 14430553380
Thus, we can understand that the LCM of 405,412,878,927,788 is 14430553380.
