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 23,503,025, 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 | 23,503,025 | |
| -1 | -23,503,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,503,025.
Example:
1 x 23,503,025 = 23,503,025
and
-1 x -23,503,025 = 23,503,025
Notice both answers equal 23,503,025
With that explanation out of the way, let's continue. Next, we take the number 23,503,025 and divide it by 2:
23,503,025 ÷ 2 = 11,751,512.5
If the quotient is a whole number, then 2 and 11,751,512.5 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 | 23,503,025 | |
| -1 | -23,503,025 |
Now, we try dividing 23,503,025 by 3:
23,503,025 ÷ 3 = 7,834,341.6667
If the quotient is a whole number, then 3 and 7,834,341.6667 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 | 23,503,025 | |
| -1 | -23,503,025 |
Let's try dividing by 4:
23,503,025 ÷ 4 = 5,875,756.25
If the quotient is a whole number, then 4 and 5,875,756.25 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 | 23,503,025 | |
| -1 | 23,503,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 25 | 35 | 65 | 91 | 175 | 325 | 455 | 2,275 | 10,331 | 51,655 | 72,317 | 134,303 | 258,275 | 361,585 | 671,515 | 940,121 | 1,807,925 | 3,357,575 | 4,700,605 | 23,503,025 |
| -1 | -5 | -7 | -13 | -25 | -35 | -65 | -91 | -175 | -325 | -455 | -2,275 | -10,331 | -51,655 | -72,317 | -134,303 | -258,275 | -361,585 | -671,515 | -940,121 | -1,807,925 | -3,357,575 | -4,700,605 | -23,503,025 |
