Find LCM of 682,891,729,210 with Prime Factorization
| 2 | 682, 891, 729, 210 |
| 3 | 341, 891, 729, 105 |
| 3 | 341, 297, 243, 35 |
| 3 | 341, 99, 81, 35 |
| 3 | 341, 33, 27, 35 |
| 11 | 341, 11, 9, 35 |
| 31, 1, 9, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 11 x 31 x 1 x 9 x 35 = 17401230
Therefore, the lowest common multiple of 682,891,729,210 is 17401230.
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.
682 x 891 x 729 x 210 = 93026975580
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
729 : 1, 3, 9, 27, 81, 243, 729
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,891,729,210, is 1.
Now, the common factors can be found like this.
682:2x 11x 31
891:3x 3x 3x 3x 11
729:3x 3x 3x 3x 3x 3
210:2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3x 11 = 5346
Therefore, the value for common factors is 5346.
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 = 93026975580/(1x5346)
LCM = 93026975580/5346
LCM = 17401230
Thus, we can understand that the LCM of 682,891,729,210 is 17401230.
