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 23,053,121, 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 | 23,053,121 | |
| -1 | -23,053,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,053,121.
Example:
1 x 23,053,121 = 23,053,121
and
-1 x -23,053,121 = 23,053,121
Notice both answers equal 23,053,121
With that explanation out of the way, let's continue. Next, we take the number 23,053,121 and divide it by 2:
23,053,121 ÷ 2 = 11,526,560.5
If the quotient is a whole number, then 2 and 11,526,560.5 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 | 23,053,121 | |
| -1 | -23,053,121 |
Now, we try dividing 23,053,121 by 3:
23,053,121 ÷ 3 = 7,684,373.6667
If the quotient is a whole number, then 3 and 7,684,373.6667 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 | 23,053,121 | |
| -1 | -23,053,121 |
Let's try dividing by 4:
23,053,121 ÷ 4 = 5,763,280.25
If the quotient is a whole number, then 4 and 5,763,280.25 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 | 23,053,121 | |
| -1 | 23,053,121 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 169 | 1,183 | 1,499 | 2,197 | 10,493 | 15,379 | 19,487 | 136,409 | 253,331 | 1,773,317 | 3,293,303 | 23,053,121 |
| -1 | -7 | -13 | -91 | -169 | -1,183 | -1,499 | -2,197 | -10,493 | -15,379 | -19,487 | -136,409 | -253,331 | -1,773,317 | -3,293,303 | -23,053,121 |
