Given numbers are 239,731,646,399
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 239,731,646,399 is 139417782.
Find LCM of 239,731,646,399 with Prime Factorization
| 17 | 239, 731, 646, 399 |
| 19 | 239, 43, 38, 399 |
| 239, 43, 2, 21 |
Multiply the prime numbers at the bottom and the left side.
17 x 19 x 239 x 43 x 2 x 21 = 139417782
Therefore, the lowest common multiple of 239,731,646,399 is 139417782.
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.
239 x 731 x 646 x 399 = 45031943586
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.
239 : 1, 239
731 : 1, 17, 43, 731
646 : 1, 2, 17, 19, 34, 38, 323, 646
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 239,731,646,399, is 1.
Now, the common factors can be found like this.
239:239
731:17x 43
646:2x 17x 19
399:3x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 19 = 323
Therefore, the value for common factors is 323.
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 = 45031943586/(1x323)
LCM = 45031943586/323
LCM = 139417782
Thus, we can understand that the LCM of 239,731,646,399 is 139417782.
