Given numbers are 837,682,889,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 837,682,889,981 is 1784335014.
Find LCM of 837,682,889,981 with Prime Factorization
| 3 | 837, 682, 889, 981 |
| 3 | 279, 682, 889, 327 |
| 31 | 93, 682, 889, 109 |
| 3, 22, 889, 109 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 31 x 3 x 22 x 889 x 109 = 1784335014
Therefore, the lowest common multiple of 837,682,889,981 is 1784335014.
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.
837 x 682 x 889 x 981 = 497829468906
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.
837 : 1, 3, 9, 27, 31, 93, 279, 837
682 : 1, 2, 11, 22, 31, 62, 341, 682
889 : 1, 7, 127, 889
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 837,682,889,981, is 1.
Now, the common factors can be found like this.
837:3x 3x 3x 31
682:2x 11x 31
889:7x 127
981:3x 3x 109
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 31 = 279
Therefore, the value for common factors is 279.
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 = 497829468906/(1x279)
LCM = 497829468906/279
LCM = 1784335014
Thus, we can understand that the LCM of 837,682,889,981 is 1784335014.
