Given numbers are 317,418,738,646,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 317,418,738,646,731 is 35742035934.
Find LCM of 317,418,738,646,731 with Prime Factorization
| 2 | 317, 418, 738, 646, 731 |
| 17 | 317, 209, 369, 323, 731 |
| 19 | 317, 209, 369, 19, 43 |
| 317, 11, 369, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 317 x 11 x 369 x 1 x 43 = 35742035934
Therefore, the lowest common multiple of 317,418,738,646,731 is 35742035934.
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.
317 x 418 x 738 x 646 x 731 = 46178710426728
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.
317 : 1, 317
418 : 1, 2, 11, 19, 22, 38, 209, 418
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
646 : 1, 2, 17, 19, 34, 38, 323, 646
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 317,418,738,646,731, is 1.
Now, the common factors can be found like this.
317:317
418:2x 11x 19
738:2x 3x 3x 41
646:2x 17x 19
731:17x 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 19 = 1292
Therefore, the value for common factors is 1292.
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 = 46178710426728/(1x1292)
LCM = 46178710426728/1292
LCM = 35742035934
Thus, we can understand that the LCM of 317,418,738,646,731 is 35742035934.
