Given numbers are 647,388,291,643,517
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,388,291,643,517 is 250356445548.
Find LCM of 647,388,291,643,517 with Prime Factorization
97 | 647, 388, 291, 643, 517 |
647, 4, 3, 643, 517 |
Multiply the prime numbers at the bottom and the left side.
97 x 647 x 4 x 3 x 643 x 517 = 250356445548
Therefore, the lowest common multiple of 647,388,291,643,517 is 250356445548.
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.
647 x 388 x 291 x 643 x 517 = 24284575218156
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.
647 : 1, 647
388 : 1, 2, 4, 97, 194, 388
291 : 1, 3, 97, 291
643 : 1, 643
517 : 1, 11, 47, 517
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,388,291,643,517, is 1.
Now, the common factors can be found like this.
647:647
388:2x 2x 97
291:3x 97
643:643
517:11x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
97 = 97
Therefore, the value for common factors is 97.
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 = 24284575218156/(1x97)
LCM = 24284575218156/97
LCM = 250356445548
Thus, we can understand that the LCM of 647,388,291,643,517 is 250356445548.
