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 23,164,075, 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 | 23,164,075 | |
| -1 | -23,164,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,164,075.
Example:
1 x 23,164,075 = 23,164,075
and
-1 x -23,164,075 = 23,164,075
Notice both answers equal 23,164,075
With that explanation out of the way, let's continue. Next, we take the number 23,164,075 and divide it by 2:
23,164,075 ÷ 2 = 11,582,037.5
If the quotient is a whole number, then 2 and 11,582,037.5 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 | 23,164,075 | |
| -1 | -23,164,075 |
Now, we try dividing 23,164,075 by 3:
23,164,075 ÷ 3 = 7,721,358.3333
If the quotient is a whole number, then 3 and 7,721,358.3333 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 | 23,164,075 | |
| -1 | -23,164,075 |
Let's try dividing by 4:
23,164,075 ÷ 4 = 5,791,018.75
If the quotient is a whole number, then 4 and 5,791,018.75 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 | 23,164,075 | |
| -1 | 23,164,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 131 | 275 | 643 | 655 | 1,441 | 3,215 | 3,275 | 7,073 | 7,205 | 16,075 | 35,365 | 36,025 | 84,233 | 176,825 | 421,165 | 926,563 | 2,105,825 | 4,632,815 | 23,164,075 |
| -1 | -5 | -11 | -25 | -55 | -131 | -275 | -643 | -655 | -1,441 | -3,215 | -3,275 | -7,073 | -7,205 | -16,075 | -35,365 | -36,025 | -84,233 | -176,825 | -421,165 | -926,563 | -2,105,825 | -4,632,815 | -23,164,075 |
