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 4,245,593, 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 | 4,245,593 | |
| -1 | -4,245,593 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,245,593.
Example:
1 x 4,245,593 = 4,245,593
and
-1 x -4,245,593 = 4,245,593
Notice both answers equal 4,245,593
With that explanation out of the way, let's continue. Next, we take the number 4,245,593 and divide it by 2:
4,245,593 ÷ 2 = 2,122,796.5
If the quotient is a whole number, then 2 and 2,122,796.5 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 | 4,245,593 | |
| -1 | -4,245,593 |
Now, we try dividing 4,245,593 by 3:
4,245,593 ÷ 3 = 1,415,197.6667
If the quotient is a whole number, then 3 and 1,415,197.6667 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 | 4,245,593 | |
| -1 | -4,245,593 |
Let's try dividing by 4:
4,245,593 ÷ 4 = 1,061,398.25
If the quotient is a whole number, then 4 and 1,061,398.25 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 | 4,245,593 | |
| -1 | 4,245,593 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 97 | 173 | 253 | 1,067 | 1,903 | 2,231 | 3,979 | 16,781 | 24,541 | 43,769 | 184,591 | 385,963 | 4,245,593 |
| -1 | -11 | -23 | -97 | -173 | -253 | -1,067 | -1,903 | -2,231 | -3,979 | -16,781 | -24,541 | -43,769 | -184,591 | -385,963 | -4,245,593 |
