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 202,733,515, 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 | 202,733,515 | |
| -1 | -202,733,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,733,515.
Example:
1 x 202,733,515 = 202,733,515
and
-1 x -202,733,515 = 202,733,515
Notice both answers equal 202,733,515
With that explanation out of the way, let's continue. Next, we take the number 202,733,515 and divide it by 2:
202,733,515 ÷ 2 = 101,366,757.5
If the quotient is a whole number, then 2 and 101,366,757.5 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 | 202,733,515 | |
| -1 | -202,733,515 |
Now, we try dividing 202,733,515 by 3:
202,733,515 ÷ 3 = 67,577,838.3333
If the quotient is a whole number, then 3 and 67,577,838.3333 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 | 202,733,515 | |
| -1 | -202,733,515 |
Let's try dividing by 4:
202,733,515 ÷ 4 = 50,683,378.75
If the quotient is a whole number, then 4 and 50,683,378.75 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 | 202,733,515 | |
| -1 | 202,733,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 1,439 | 1,483 | 7,195 | 7,415 | 27,341 | 28,177 | 136,705 | 140,885 | 2,134,037 | 10,670,185 | 40,546,703 | 202,733,515 |
| -1 | -5 | -19 | -95 | -1,439 | -1,483 | -7,195 | -7,415 | -27,341 | -28,177 | -136,705 | -140,885 | -2,134,037 | -10,670,185 | -40,546,703 | -202,733,515 |
