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 23,053,525, 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 | 23,053,525 | |
| -1 | -23,053,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,053,525.
Example:
1 x 23,053,525 = 23,053,525
and
-1 x -23,053,525 = 23,053,525
Notice both answers equal 23,053,525
With that explanation out of the way, let's continue. Next, we take the number 23,053,525 and divide it by 2:
23,053,525 ÷ 2 = 11,526,762.5
If the quotient is a whole number, then 2 and 11,526,762.5 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 | 23,053,525 | |
| -1 | -23,053,525 |
Now, we try dividing 23,053,525 by 3:
23,053,525 ÷ 3 = 7,684,508.3333
If the quotient is a whole number, then 3 and 7,684,508.3333 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 | 23,053,525 | |
| -1 | -23,053,525 |
Let's try dividing by 4:
23,053,525 ÷ 4 = 5,763,381.25
If the quotient is a whole number, then 4 and 5,763,381.25 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 | 23,053,525 | |
| -1 | 23,053,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 121 | 275 | 605 | 3,025 | 7,621 | 38,105 | 83,831 | 190,525 | 419,155 | 922,141 | 2,095,775 | 4,610,705 | 23,053,525 |
| -1 | -5 | -11 | -25 | -55 | -121 | -275 | -605 | -3,025 | -7,621 | -38,105 | -83,831 | -190,525 | -419,155 | -922,141 | -2,095,775 | -4,610,705 | -23,053,525 |
