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 223,514,155, 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 | 223,514,155 | |
| -1 | -223,514,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 223,514,155.
Example:
1 x 223,514,155 = 223,514,155
and
-1 x -223,514,155 = 223,514,155
Notice both answers equal 223,514,155
With that explanation out of the way, let's continue. Next, we take the number 223,514,155 and divide it by 2:
223,514,155 ÷ 2 = 111,757,077.5
If the quotient is a whole number, then 2 and 111,757,077.5 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 | 223,514,155 | |
| -1 | -223,514,155 |
Now, we try dividing 223,514,155 by 3:
223,514,155 ÷ 3 = 74,504,718.3333
If the quotient is a whole number, then 3 and 74,504,718.3333 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 | 223,514,155 | |
| -1 | -223,514,155 |
Let's try dividing by 4:
223,514,155 ÷ 4 = 55,878,538.75
If the quotient is a whole number, then 4 and 55,878,538.75 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 | 223,514,155 | |
| -1 | 223,514,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 149 | 445 | 745 | 3,371 | 13,261 | 16,855 | 66,305 | 300,019 | 502,279 | 1,500,095 | 2,511,395 | 44,702,831 | 223,514,155 |
| -1 | -5 | -89 | -149 | -445 | -745 | -3,371 | -13,261 | -16,855 | -66,305 | -300,019 | -502,279 | -1,500,095 | -2,511,395 | -44,702,831 | -223,514,155 |
