Find LCM of 825,120,858,738,729 with Prime Factorization
| 2 | 825, 120, 858, 738, 729 |
| 3 | 825, 60, 429, 369, 729 |
| 3 | 275, 20, 143, 123, 243 |
| 5 | 275, 20, 143, 41, 81 |
| 11 | 55, 4, 143, 41, 81 |
| 5, 4, 13, 41, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 5 x 4 x 13 x 41 x 81 = 854825400
Therefore, the lowest common multiple of 825,120,858,738,729 is 854825400.
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.
825 x 120 x 858 x 738 x 729 = 45698965884000
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.
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
729 : 1, 3, 9, 27, 81, 243, 729
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 825,120,858,738,729, is 3.
Now, the common factors can be found like this.
825:3x 5x 5x 11
120:2x 2x 2x 3x 5
858:2x 3x 11x 13
738:2x 3x 3x 41
729:3x 3x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 3x 5x 11 = 17820
Therefore, the value for common factors is 17820.
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 = 45698965884000/(3x17820)
LCM = 45698965884000/53460
LCM = 854825400
Thus, we can understand that the LCM of 825,120,858,738,729 is 854825400.
