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 23,450,525, 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 | 23,450,525 | |
| -1 | -23,450,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,450,525.
Example:
1 x 23,450,525 = 23,450,525
and
-1 x -23,450,525 = 23,450,525
Notice both answers equal 23,450,525
With that explanation out of the way, let's continue. Next, we take the number 23,450,525 and divide it by 2:
23,450,525 ÷ 2 = 11,725,262.5
If the quotient is a whole number, then 2 and 11,725,262.5 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 | 23,450,525 | |
| -1 | -23,450,525 |
Now, we try dividing 23,450,525 by 3:
23,450,525 ÷ 3 = 7,816,841.6667
If the quotient is a whole number, then 3 and 7,816,841.6667 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 | 23,450,525 | |
| -1 | -23,450,525 |
Let's try dividing by 4:
23,450,525 ÷ 4 = 5,862,631.25
If the quotient is a whole number, then 4 and 5,862,631.25 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 | 23,450,525 | |
| -1 | 23,450,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 103 | 175 | 515 | 721 | 1,301 | 2,575 | 3,605 | 6,505 | 9,107 | 18,025 | 32,525 | 45,535 | 134,003 | 227,675 | 670,015 | 938,021 | 3,350,075 | 4,690,105 | 23,450,525 |
| -1 | -5 | -7 | -25 | -35 | -103 | -175 | -515 | -721 | -1,301 | -2,575 | -3,605 | -6,505 | -9,107 | -18,025 | -32,525 | -45,535 | -134,003 | -227,675 | -670,015 | -938,021 | -3,350,075 | -4,690,105 | -23,450,525 |
