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 202,051,459, 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 | 202,051,459 | |
| -1 | -202,051,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,051,459.
Example:
1 x 202,051,459 = 202,051,459
and
-1 x -202,051,459 = 202,051,459
Notice both answers equal 202,051,459
With that explanation out of the way, let's continue. Next, we take the number 202,051,459 and divide it by 2:
202,051,459 ÷ 2 = 101,025,729.5
If the quotient is a whole number, then 2 and 101,025,729.5 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 | 202,051,459 | |
| -1 | -202,051,459 |
Now, we try dividing 202,051,459 by 3:
202,051,459 ÷ 3 = 67,350,486.3333
If the quotient is a whole number, then 3 and 67,350,486.3333 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 | 202,051,459 | |
| -1 | -202,051,459 |
Let's try dividing by 4:
202,051,459 ÷ 4 = 50,512,864.75
If the quotient is a whole number, then 4 and 50,512,864.75 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 | 202,051,459 | |
| -1 | 202,051,459 |
If you did it right, you will end up with this table:
| 1 | 31 | 59 | 61 | 1,811 | 1,829 | 1,891 | 3,599 | 56,141 | 106,849 | 110,471 | 111,569 | 3,312,319 | 3,424,601 | 6,517,789 | 202,051,459 |
| -1 | -31 | -59 | -61 | -1,811 | -1,829 | -1,891 | -3,599 | -56,141 | -106,849 | -110,471 | -111,569 | -3,312,319 | -3,424,601 | -6,517,789 | -202,051,459 |
