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 23,400,355, 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 | 23,400,355 | |
| -1 | -23,400,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,400,355.
Example:
1 x 23,400,355 = 23,400,355
and
-1 x -23,400,355 = 23,400,355
Notice both answers equal 23,400,355
With that explanation out of the way, let's continue. Next, we take the number 23,400,355 and divide it by 2:
23,400,355 ÷ 2 = 11,700,177.5
If the quotient is a whole number, then 2 and 11,700,177.5 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 | 23,400,355 | |
| -1 | -23,400,355 |
Now, we try dividing 23,400,355 by 3:
23,400,355 ÷ 3 = 7,800,118.3333
If the quotient is a whole number, then 3 and 7,800,118.3333 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 | 23,400,355 | |
| -1 | -23,400,355 |
Let's try dividing by 4:
23,400,355 ÷ 4 = 5,850,088.75
If the quotient is a whole number, then 4 and 5,850,088.75 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 | 23,400,355 | |
| -1 | 23,400,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 401 | 1,061 | 2,005 | 4,411 | 5,305 | 11,671 | 22,055 | 58,355 | 425,461 | 2,127,305 | 4,680,071 | 23,400,355 |
| -1 | -5 | -11 | -55 | -401 | -1,061 | -2,005 | -4,411 | -5,305 | -11,671 | -22,055 | -58,355 | -425,461 | -2,127,305 | -4,680,071 | -23,400,355 |
