Given numbers are 398,131,939,574,493
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,131,939,574,493 is 6927057234762.
Find LCM of 398,131,939,574,493 with Prime Factorization
| 2 | 398, 131, 939, 574, 493 |
| 199, 131, 939, 287, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 199 x 131 x 939 x 287 x 493 = 6927057234762
Therefore, the lowest common multiple of 398,131,939,574,493 is 6927057234762.
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.
398 x 131 x 939 x 574 x 493 = 13854114469524
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.
398 : 1, 2, 199, 398
131 : 1, 131
939 : 1, 3, 313, 939
574 : 1, 2, 7, 14, 41, 82, 287, 574
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,131,939,574,493, is 1.
Now, the common factors can be found like this.
398:2x 199
131:131
939:3x 313
574:2x 7x 41
493:17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 13854114469524/(1x2)
LCM = 13854114469524/2
LCM = 6927057234762
Thus, we can understand that the LCM of 398,131,939,574,493 is 6927057234762.
