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 23,011,435, 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 | 23,011,435 | |
| -1 | -23,011,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,011,435.
Example:
1 x 23,011,435 = 23,011,435
and
-1 x -23,011,435 = 23,011,435
Notice both answers equal 23,011,435
With that explanation out of the way, let's continue. Next, we take the number 23,011,435 and divide it by 2:
23,011,435 ÷ 2 = 11,505,717.5
If the quotient is a whole number, then 2 and 11,505,717.5 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 | 23,011,435 | |
| -1 | -23,011,435 |
Now, we try dividing 23,011,435 by 3:
23,011,435 ÷ 3 = 7,670,478.3333
If the quotient is a whole number, then 3 and 7,670,478.3333 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 | 23,011,435 | |
| -1 | -23,011,435 |
Let's try dividing by 4:
23,011,435 ÷ 4 = 5,752,858.75
If the quotient is a whole number, then 4 and 5,752,858.75 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 | 23,011,435 | |
| -1 | 23,011,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 181 | 235 | 541 | 905 | 2,705 | 8,507 | 25,427 | 42,535 | 97,921 | 127,135 | 489,605 | 4,602,287 | 23,011,435 |
| -1 | -5 | -47 | -181 | -235 | -541 | -905 | -2,705 | -8,507 | -25,427 | -42,535 | -97,921 | -127,135 | -489,605 | -4,602,287 | -23,011,435 |
