Given numbers are 818,137,638,844
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 818,137,638,844 is 15086100788.
Find LCM of 818,137,638,844 with Prime Factorization
| 2 | 818, 137, 638, 844 |
| 409, 137, 319, 422 |
Multiply the prime numbers at the bottom and the left side.
2 x 409 x 137 x 319 x 422 = 15086100788
Therefore, the lowest common multiple of 818,137,638,844 is 15086100788.
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.
818 x 137 x 638 x 844 = 60344403152
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.
818 : 1, 2, 409, 818
137 : 1, 137
638 : 1, 2, 11, 22, 29, 58, 319, 638
844 : 1, 2, 4, 211, 422, 844
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,137,638,844, is 1.
Now, the common factors can be found like this.
818:2x 409
137:137
638:2x 11x 29
844:2x 2x 211
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 60344403152/(1x4)
LCM = 60344403152/4
LCM = 15086100788
Thus, we can understand that the LCM of 818,137,638,844 is 15086100788.
