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 4,136,785, 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 | 4,136,785 | |
| -1 | -4,136,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,136,785.
Example:
1 x 4,136,785 = 4,136,785
and
-1 x -4,136,785 = 4,136,785
Notice both answers equal 4,136,785
With that explanation out of the way, let's continue. Next, we take the number 4,136,785 and divide it by 2:
4,136,785 ÷ 2 = 2,068,392.5
If the quotient is a whole number, then 2 and 2,068,392.5 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 | 4,136,785 | |
| -1 | -4,136,785 |
Now, we try dividing 4,136,785 by 3:
4,136,785 ÷ 3 = 1,378,928.3333
If the quotient is a whole number, then 3 and 1,378,928.3333 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 | 4,136,785 | |
| -1 | -4,136,785 |
Let's try dividing by 4:
4,136,785 ÷ 4 = 1,034,196.25
If the quotient is a whole number, then 4 and 1,034,196.25 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 | 4,136,785 | |
| -1 | 4,136,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 59 | 185 | 295 | 379 | 1,895 | 2,183 | 10,915 | 14,023 | 22,361 | 70,115 | 111,805 | 827,357 | 4,136,785 |
| -1 | -5 | -37 | -59 | -185 | -295 | -379 | -1,895 | -2,183 | -10,915 | -14,023 | -22,361 | -70,115 | -111,805 | -827,357 | -4,136,785 |
