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 202,152,353, 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 | 202,152,353 | |
| -1 | -202,152,353 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,152,353.
Example:
1 x 202,152,353 = 202,152,353
and
-1 x -202,152,353 = 202,152,353
Notice both answers equal 202,152,353
With that explanation out of the way, let's continue. Next, we take the number 202,152,353 and divide it by 2:
202,152,353 ÷ 2 = 101,076,176.5
If the quotient is a whole number, then 2 and 101,076,176.5 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 | 202,152,353 | |
| -1 | -202,152,353 |
Now, we try dividing 202,152,353 by 3:
202,152,353 ÷ 3 = 67,384,117.6667
If the quotient is a whole number, then 3 and 67,384,117.6667 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 | 202,152,353 | |
| -1 | -202,152,353 |
Let's try dividing by 4:
202,152,353 ÷ 4 = 50,538,088.25
If the quotient is a whole number, then 4 and 50,538,088.25 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 | 202,152,353 | |
| -1 | 202,152,353 |
If you did it right, you will end up with this table:
| 1 | 13 | 61 | 227 | 793 | 1,123 | 2,951 | 13,847 | 14,599 | 68,503 | 180,011 | 254,921 | 890,539 | 3,313,973 | 15,550,181 | 202,152,353 |
| -1 | -13 | -61 | -227 | -793 | -1,123 | -2,951 | -13,847 | -14,599 | -68,503 | -180,011 | -254,921 | -890,539 | -3,313,973 | -15,550,181 | -202,152,353 |
