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 23,045,455, 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 | 23,045,455 | |
| -1 | -23,045,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,045,455.
Example:
1 x 23,045,455 = 23,045,455
and
-1 x -23,045,455 = 23,045,455
Notice both answers equal 23,045,455
With that explanation out of the way, let's continue. Next, we take the number 23,045,455 and divide it by 2:
23,045,455 ÷ 2 = 11,522,727.5
If the quotient is a whole number, then 2 and 11,522,727.5 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 | 23,045,455 | |
| -1 | -23,045,455 |
Now, we try dividing 23,045,455 by 3:
23,045,455 ÷ 3 = 7,681,818.3333
If the quotient is a whole number, then 3 and 7,681,818.3333 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 | 23,045,455 | |
| -1 | -23,045,455 |
Let's try dividing by 4:
23,045,455 ÷ 4 = 5,761,363.75
If the quotient is a whole number, then 4 and 5,761,363.75 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 | 23,045,455 | |
| -1 | 23,045,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 137 | 685 | 1,979 | 2,329 | 9,895 | 11,645 | 33,643 | 168,215 | 271,123 | 1,355,615 | 4,609,091 | 23,045,455 |
| -1 | -5 | -17 | -85 | -137 | -685 | -1,979 | -2,329 | -9,895 | -11,645 | -33,643 | -168,215 | -271,123 | -1,355,615 | -4,609,091 | -23,045,455 |
