Given numbers are 338,394,639,188,401
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,394,639,188,401 is 1603821425076.
Find LCM of 338,394,639,188,401 with Prime Factorization
| 2 | 338, 394, 639, 188, 401 |
| 169, 197, 639, 94, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 169 x 197 x 639 x 94 x 401 = 1603821425076
Therefore, the lowest common multiple of 338,394,639,188,401 is 1603821425076.
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.
338 x 394 x 639 x 188 x 401 = 6415285700304
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.
338 : 1, 2, 13, 26, 169, 338
394 : 1, 2, 197, 394
639 : 1, 3, 9, 71, 213, 639
188 : 1, 2, 4, 47, 94, 188
401 : 1, 401
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,394,639,188,401, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
394:2x 197
639:3x 3x 71
188:2x 2x 47
401:401
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 6415285700304/(1x4)
LCM = 6415285700304/4
LCM = 1603821425076
Thus, we can understand that the LCM of 338,394,639,188,401 is 1603821425076.
