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 23,103,355, 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 | 23,103,355 | |
| -1 | -23,103,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,103,355.
Example:
1 x 23,103,355 = 23,103,355
and
-1 x -23,103,355 = 23,103,355
Notice both answers equal 23,103,355
With that explanation out of the way, let's continue. Next, we take the number 23,103,355 and divide it by 2:
23,103,355 ÷ 2 = 11,551,677.5
If the quotient is a whole number, then 2 and 11,551,677.5 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 | 23,103,355 | |
| -1 | -23,103,355 |
Now, we try dividing 23,103,355 by 3:
23,103,355 ÷ 3 = 7,701,118.3333
If the quotient is a whole number, then 3 and 7,701,118.3333 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 | 23,103,355 | |
| -1 | -23,103,355 |
Let's try dividing by 4:
23,103,355 ÷ 4 = 5,775,838.75
If the quotient is a whole number, then 4 and 5,775,838.75 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 | 23,103,355 | |
| -1 | 23,103,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 37 | 55 | 185 | 407 | 2,035 | 11,353 | 56,765 | 124,883 | 420,061 | 624,415 | 2,100,305 | 4,620,671 | 23,103,355 |
| -1 | -5 | -11 | -37 | -55 | -185 | -407 | -2,035 | -11,353 | -56,765 | -124,883 | -420,061 | -624,415 | -2,100,305 | -4,620,671 | -23,103,355 |
