Given numbers are 394,816,268,997,238
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 394,816,268,997,238 is 75166509936.
Find LCM of 394,816,268,997,238 with Prime Factorization
| 2 | 394, 816, 268, 997, 238 |
| 2 | 197, 408, 134, 997, 119 |
| 17 | 197, 204, 67, 997, 119 |
| 197, 12, 67, 997, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 197 x 12 x 67 x 997 x 7 = 75166509936
Therefore, the lowest common multiple of 394,816,268,997,238 is 75166509936.
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.
394 x 816 x 268 x 997 x 238 = 20445290702592
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.
394 : 1, 2, 197, 394
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
268 : 1, 2, 4, 67, 134, 268
997 : 1, 997
238 : 1, 2, 7, 14, 17, 34, 119, 238
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,816,268,997,238, is 1.
Now, the common factors can be found like this.
394:2x 197
816:2x 2x 2x 2x 3x 17
268:2x 2x 67
997:997
238:2x 7x 17
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 2x 2x 17 = 272
Therefore, the value for common factors is 272.
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 = 20445290702592/(1x272)
LCM = 20445290702592/272
LCM = 75166509936
Thus, we can understand that the LCM of 394,816,268,997,238 is 75166509936.
