Given numbers are 412,646,731,390,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 412,646,731,390,817 is 1115842260.
Find LCM of 412,646,731,390,817 with Prime Factorization
| 2 | 412, 646, 731, 390, 817 |
| 17 | 206, 323, 731, 195, 817 |
| 19 | 206, 19, 43, 195, 817 |
| 43 | 206, 1, 43, 195, 43 |
| 206, 1, 1, 195, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 43 x 206 x 1 x 1 x 195 x 1 = 1115842260
Therefore, the lowest common multiple of 412,646,731,390,817 is 1115842260.
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.
412 x 646 x 731 x 390 x 817 = 61991732596560
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.
412 : 1, 2, 4, 103, 206, 412
646 : 1, 2, 17, 19, 34, 38, 323, 646
731 : 1, 17, 43, 731
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 412,646,731,390,817, is 1.
Now, the common factors can be found like this.
412:2x 2x 103
646:2x 17x 19
731:17x 43
390:2x 3x 5x 13
817:19x 43
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 17x 19x 43 = 55556
Therefore, the value for common factors is 55556.
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 = 61991732596560/(1x55556)
LCM = 61991732596560/55556
LCM = 1115842260
Thus, we can understand that the LCM of 412,646,731,390,817 is 1115842260.
