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 202,102,303, 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 | 202,102,303 | |
| -1 | -202,102,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,102,303.
Example:
1 x 202,102,303 = 202,102,303
and
-1 x -202,102,303 = 202,102,303
Notice both answers equal 202,102,303
With that explanation out of the way, let's continue. Next, we take the number 202,102,303 and divide it by 2:
202,102,303 ÷ 2 = 101,051,151.5
If the quotient is a whole number, then 2 and 101,051,151.5 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 | 202,102,303 | |
| -1 | -202,102,303 |
Now, we try dividing 202,102,303 by 3:
202,102,303 ÷ 3 = 67,367,434.3333
If the quotient is a whole number, then 3 and 67,367,434.3333 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 | 202,102,303 | |
| -1 | -202,102,303 |
Let's try dividing by 4:
202,102,303 ÷ 4 = 50,525,575.75
If the quotient is a whole number, then 4 and 50,525,575.75 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 | 202,102,303 | |
| -1 | 202,102,303 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 53 | 79 | 611 | 689 | 1,027 | 2,491 | 3,713 | 4,187 | 6,241 | 32,383 | 48,269 | 54,431 | 81,133 | 196,789 | 293,327 | 330,773 | 2,558,257 | 3,813,251 | 4,300,049 | 15,546,331 | 202,102,303 |
| -1 | -13 | -47 | -53 | -79 | -611 | -689 | -1,027 | -2,491 | -3,713 | -4,187 | -6,241 | -32,383 | -48,269 | -54,431 | -81,133 | -196,789 | -293,327 | -330,773 | -2,558,257 | -3,813,251 | -4,300,049 | -15,546,331 | -202,102,303 |
