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 223,176,569, 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 | 223,176,569 | |
| -1 | -223,176,569 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 223,176,569.
Example:
1 x 223,176,569 = 223,176,569
and
-1 x -223,176,569 = 223,176,569
Notice both answers equal 223,176,569
With that explanation out of the way, let's continue. Next, we take the number 223,176,569 and divide it by 2:
223,176,569 ÷ 2 = 111,588,284.5
If the quotient is a whole number, then 2 and 111,588,284.5 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 | 223,176,569 | |
| -1 | -223,176,569 |
Now, we try dividing 223,176,569 by 3:
223,176,569 ÷ 3 = 74,392,189.6667
If the quotient is a whole number, then 3 and 74,392,189.6667 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 | 223,176,569 | |
| -1 | -223,176,569 |
Let's try dividing by 4:
223,176,569 ÷ 4 = 55,794,142.25
If the quotient is a whole number, then 4 and 55,794,142.25 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 | 223,176,569 | |
| -1 | 223,176,569 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 101 | 707 | 1,111 | 7,777 | 28,697 | 200,879 | 315,667 | 2,209,669 | 2,898,397 | 20,288,779 | 31,882,367 | 223,176,569 |
| -1 | -7 | -11 | -77 | -101 | -707 | -1,111 | -7,777 | -28,697 | -200,879 | -315,667 | -2,209,669 | -2,898,397 | -20,288,779 | -31,882,367 | -223,176,569 |
