Given numbers are 393,143,771,873,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 393,143,771,873,388 is 16811818452.
Find LCM of 393,143,771,873,388 with Prime Factorization
| 3 | 393, 143, 771, 873, 388 |
| 97 | 131, 143, 257, 291, 388 |
| 131, 143, 257, 3, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 97 x 131 x 143 x 257 x 3 x 4 = 16811818452
Therefore, the lowest common multiple of 393,143,771,873,388 is 16811818452.
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.
393 x 143 x 771 x 873 x 388 = 14676717508596
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.
393 : 1, 3, 131, 393
143 : 1, 11, 13, 143
771 : 1, 3, 257, 771
873 : 1, 3, 9, 97, 291, 873
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,143,771,873,388, is 1.
Now, the common factors can be found like this.
393:3x 131
143:11x 13
771:3x 257
873:3x 3x 97
388:2x 2x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 97 = 873
Therefore, the value for common factors is 873.
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 = 14676717508596/(1x873)
LCM = 14676717508596/873
LCM = 16811818452
Thus, we can understand that the LCM of 393,143,771,873,388 is 16811818452.
