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 202,213,033, 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 | 202,213,033 | |
| -1 | -202,213,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,213,033.
Example:
1 x 202,213,033 = 202,213,033
and
-1 x -202,213,033 = 202,213,033
Notice both answers equal 202,213,033
With that explanation out of the way, let's continue. Next, we take the number 202,213,033 and divide it by 2:
202,213,033 ÷ 2 = 101,106,516.5
If the quotient is a whole number, then 2 and 101,106,516.5 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 | 202,213,033 | |
| -1 | -202,213,033 |
Now, we try dividing 202,213,033 by 3:
202,213,033 ÷ 3 = 67,404,344.3333
If the quotient is a whole number, then 3 and 67,404,344.3333 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 | 202,213,033 | |
| -1 | -202,213,033 |
Let's try dividing by 4:
202,213,033 ÷ 4 = 50,553,258.25
If the quotient is a whole number, then 4 and 50,553,258.25 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 | 202,213,033 | |
| -1 | 202,213,033 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 253 | 853 | 937 | 9,383 | 10,307 | 19,619 | 21,551 | 215,809 | 237,061 | 799,261 | 8,791,871 | 18,383,003 | 202,213,033 |
| -1 | -11 | -23 | -253 | -853 | -937 | -9,383 | -10,307 | -19,619 | -21,551 | -215,809 | -237,061 | -799,261 | -8,791,871 | -18,383,003 | -202,213,033 |
