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 223,119,995, 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 | 223,119,995 | |
| -1 | -223,119,995 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 223,119,995.
Example:
1 x 223,119,995 = 223,119,995
and
-1 x -223,119,995 = 223,119,995
Notice both answers equal 223,119,995
With that explanation out of the way, let's continue. Next, we take the number 223,119,995 and divide it by 2:
223,119,995 ÷ 2 = 111,559,997.5
If the quotient is a whole number, then 2 and 111,559,997.5 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 | 223,119,995 | |
| -1 | -223,119,995 |
Now, we try dividing 223,119,995 by 3:
223,119,995 ÷ 3 = 74,373,331.6667
If the quotient is a whole number, then 3 and 74,373,331.6667 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 | 223,119,995 | |
| -1 | -223,119,995 |
Let's try dividing by 4:
223,119,995 ÷ 4 = 55,779,998.75
If the quotient is a whole number, then 4 and 55,779,998.75 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 | 223,119,995 | |
| -1 | 223,119,995 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 263 | 1,315 | 1,841 | 9,205 | 24,239 | 121,195 | 169,673 | 848,365 | 6,374,857 | 31,874,285 | 44,623,999 | 223,119,995 |
| -1 | -5 | -7 | -35 | -263 | -1,315 | -1,841 | -9,205 | -24,239 | -121,195 | -169,673 | -848,365 | -6,374,857 | -31,874,285 | -44,623,999 | -223,119,995 |
