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 23,165,345, 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 | 23,165,345 | |
| -1 | -23,165,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,165,345.
Example:
1 x 23,165,345 = 23,165,345
and
-1 x -23,165,345 = 23,165,345
Notice both answers equal 23,165,345
With that explanation out of the way, let's continue. Next, we take the number 23,165,345 and divide it by 2:
23,165,345 ÷ 2 = 11,582,672.5
If the quotient is a whole number, then 2 and 11,582,672.5 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 | 23,165,345 | |
| -1 | -23,165,345 |
Now, we try dividing 23,165,345 by 3:
23,165,345 ÷ 3 = 7,721,781.6667
If the quotient is a whole number, then 3 and 7,721,781.6667 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 | 23,165,345 | |
| -1 | -23,165,345 |
Let's try dividing by 4:
23,165,345 ÷ 4 = 5,791,336.25
If the quotient is a whole number, then 4 and 5,791,336.25 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 | 23,165,345 | |
| -1 | 23,165,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 787 | 841 | 1,015 | 3,935 | 4,205 | 5,509 | 5,887 | 22,823 | 27,545 | 29,435 | 114,115 | 159,761 | 661,867 | 798,805 | 3,309,335 | 4,633,069 | 23,165,345 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -787 | -841 | -1,015 | -3,935 | -4,205 | -5,509 | -5,887 | -22,823 | -27,545 | -29,435 | -114,115 | -159,761 | -661,867 | -798,805 | -3,309,335 | -4,633,069 | -23,165,345 |
