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 223,030,201, 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 | 223,030,201 | |
| -1 | -223,030,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 223,030,201.
Example:
1 x 223,030,201 = 223,030,201
and
-1 x -223,030,201 = 223,030,201
Notice both answers equal 223,030,201
With that explanation out of the way, let's continue. Next, we take the number 223,030,201 and divide it by 2:
223,030,201 ÷ 2 = 111,515,100.5
If the quotient is a whole number, then 2 and 111,515,100.5 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 | 223,030,201 | |
| -1 | -223,030,201 |
Now, we try dividing 223,030,201 by 3:
223,030,201 ÷ 3 = 74,343,400.3333
If the quotient is a whole number, then 3 and 74,343,400.3333 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 | 223,030,201 | |
| -1 | -223,030,201 |
Let's try dividing by 4:
223,030,201 ÷ 4 = 55,757,550.25
If the quotient is a whole number, then 4 and 55,757,550.25 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 | 223,030,201 | |
| -1 | 223,030,201 |
If you did it right, you will end up with this table:
| 1 | 41 | 53 | 197 | 521 | 2,173 | 8,077 | 10,441 | 21,361 | 27,613 | 102,637 | 428,081 | 1,132,133 | 4,208,117 | 5,439,761 | 223,030,201 |
| -1 | -41 | -53 | -197 | -521 | -2,173 | -8,077 | -10,441 | -21,361 | -27,613 | -102,637 | -428,081 | -1,132,133 | -4,208,117 | -5,439,761 | -223,030,201 |
