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 2,315,335, 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 | 2,315,335 | |
| -1 | -2,315,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,315,335.
Example:
1 x 2,315,335 = 2,315,335
and
-1 x -2,315,335 = 2,315,335
Notice both answers equal 2,315,335
With that explanation out of the way, let's continue. Next, we take the number 2,315,335 and divide it by 2:
2,315,335 ÷ 2 = 1,157,667.5
If the quotient is a whole number, then 2 and 1,157,667.5 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 | 2,315,335 | |
| -1 | -2,315,335 |
Now, we try dividing 2,315,335 by 3:
2,315,335 ÷ 3 = 771,778.3333
If the quotient is a whole number, then 3 and 771,778.3333 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 | 2,315,335 | |
| -1 | -2,315,335 |
Let's try dividing by 4:
2,315,335 ÷ 4 = 578,833.75
If the quotient is a whole number, then 4 and 578,833.75 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 | 2,315,335 | |
| -1 | 2,315,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 43 | 55 | 89 | 121 | 215 | 445 | 473 | 605 | 979 | 2,365 | 3,827 | 4,895 | 5,203 | 10,769 | 19,135 | 26,015 | 42,097 | 53,845 | 210,485 | 463,067 | 2,315,335 |
| -1 | -5 | -11 | -43 | -55 | -89 | -121 | -215 | -445 | -473 | -605 | -979 | -2,365 | -3,827 | -4,895 | -5,203 | -10,769 | -19,135 | -26,015 | -42,097 | -53,845 | -210,485 | -463,067 | -2,315,335 |
