Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 2,568,629, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 2,568,629 | |
| -1 | -2,568,629 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,568,629.
Example:
1 x 2,568,629 = 2,568,629
and
-1 x -2,568,629 = 2,568,629
Notice both answers equal 2,568,629
With that explanation out of the way, let's continue. Next, we take the number 2,568,629 and divide it by 2:
2,568,629 ÷ 2 = 1,284,314.5
If the quotient is a whole number, then 2 and 1,284,314.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 2,568,629 | |
| -1 | -2,568,629 |
Now, we try dividing 2,568,629 by 3:
2,568,629 ÷ 3 = 856,209.6667
If the quotient is a whole number, then 3 and 856,209.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 2,568,629 | |
| -1 | -2,568,629 |
Let's try dividing by 4:
2,568,629 ÷ 4 = 642,157.25
If the quotient is a whole number, then 4 and 642,157.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 2,568,629 | |
| -1 | 2,568,629 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 31 | 49 | 89 | 133 | 217 | 589 | 623 | 931 | 1,519 | 1,691 | 2,759 | 4,123 | 4,361 | 11,837 | 19,313 | 28,861 | 52,421 | 82,859 | 135,191 | 366,947 | 2,568,629 |
| -1 | -7 | -19 | -31 | -49 | -89 | -133 | -217 | -589 | -623 | -931 | -1,519 | -1,691 | -2,759 | -4,123 | -4,361 | -11,837 | -19,313 | -28,861 | -52,421 | -82,859 | -135,191 | -366,947 | -2,568,629 |
