Given numbers are 819,643,361,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 819,643,361,817 is 8174675691.
Find LCM of 819,643,361,817 with Prime Factorization
| 19 | 819, 643, 361, 817 |
| 819, 643, 19, 43 |
Multiply the prime numbers at the bottom and the left side.
19 x 819 x 643 x 19 x 43 = 8174675691
Therefore, the lowest common multiple of 819,643,361,817 is 8174675691.
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.
819 x 643 x 361 x 817 = 155318838129
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
643 : 1, 643
361 : 1, 19, 361
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,643,361,817, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
643:643
361:19x 19
817:19x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 155318838129/(1x19)
LCM = 155318838129/19
LCM = 8174675691
Thus, we can understand that the LCM of 819,643,361,817 is 8174675691.
