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 223,502,741, 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 | 223,502,741 | |
| -1 | -223,502,741 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 223,502,741.
Example:
1 x 223,502,741 = 223,502,741
and
-1 x -223,502,741 = 223,502,741
Notice both answers equal 223,502,741
With that explanation out of the way, let's continue. Next, we take the number 223,502,741 and divide it by 2:
223,502,741 ÷ 2 = 111,751,370.5
If the quotient is a whole number, then 2 and 111,751,370.5 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 | 223,502,741 | |
| -1 | -223,502,741 |
Now, we try dividing 223,502,741 by 3:
223,502,741 ÷ 3 = 74,500,913.6667
If the quotient is a whole number, then 3 and 74,500,913.6667 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 | 223,502,741 | |
| -1 | -223,502,741 |
Let's try dividing by 4:
223,502,741 ÷ 4 = 55,875,685.25
If the quotient is a whole number, then 4 and 55,875,685.25 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 | 223,502,741 | |
| -1 | 223,502,741 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 349 | 2,443 | 3,839 | 8,317 | 26,873 | 58,219 | 91,487 | 640,409 | 2,902,633 | 20,318,431 | 31,928,963 | 223,502,741 |
| -1 | -7 | -11 | -77 | -349 | -2,443 | -3,839 | -8,317 | -26,873 | -58,219 | -91,487 | -640,409 | -2,902,633 | -20,318,431 | -31,928,963 | -223,502,741 |
