Given numbers are 517,643,639,637,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 517,643,639,637,805 is 15561076826295.
Find LCM of 517,643,639,637,805 with Prime Factorization
| 7 | 517, 643, 639, 637, 805 |
| 517, 643, 639, 91, 115 |
Multiply the prime numbers at the bottom and the left side.
7 x 517 x 643 x 639 x 91 x 115 = 15561076826295
Therefore, the lowest common multiple of 517,643,639,637,805 is 15561076826295.
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.
517 x 643 x 639 x 637 x 805 = 108927537784065
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.
517 : 1, 11, 47, 517
643 : 1, 643
639 : 1, 3, 9, 71, 213, 639
637 : 1, 7, 13, 49, 91, 637
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,643,639,637,805, is 1.
Now, the common factors can be found like this.
517:11x 47
643:643
639:3x 3x 71
637:7x 7x 13
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 108927537784065/(1x7)
LCM = 108927537784065/7
LCM = 15561076826295
Thus, we can understand that the LCM of 517,643,639,637,805 is 15561076826295.
