Find LCM of 858,885,825,785,289 with Prime Factorization
| 3 | 858, 885, 825, 785, 289 |
| 5 | 286, 295, 275, 785, 289 |
| 11 | 286, 59, 55, 157, 289 |
| 26, 59, 5, 157, 289 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 26 x 59 x 5 x 157 x 289 = 57421800150
Therefore, the lowest common multiple of 858,885,825,785,289 is 57421800150.
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.
858 x 885 x 825 x 785 x 289 = 142118955371250
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
885 : 1, 3, 5, 15, 59, 177, 295, 885
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
785 : 1, 5, 157, 785
289 : 1, 17, 289
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,885,825,785,289, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
885:3x 5x 59
825:3x 5x 5x 11
785:5x 157
289:17x 17
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 5x 5x 11 = 2475
Therefore, the value for common factors is 2475.
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 = 142118955371250/(1x2475)
LCM = 142118955371250/2475
LCM = 57421800150
Thus, we can understand that the LCM of 858,885,825,785,289 is 57421800150.
