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 202,426,757, 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 | 202,426,757 | |
| -1 | -202,426,757 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,426,757.
Example:
1 x 202,426,757 = 202,426,757
and
-1 x -202,426,757 = 202,426,757
Notice both answers equal 202,426,757
With that explanation out of the way, let's continue. Next, we take the number 202,426,757 and divide it by 2:
202,426,757 ÷ 2 = 101,213,378.5
If the quotient is a whole number, then 2 and 101,213,378.5 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 | 202,426,757 | |
| -1 | -202,426,757 |
Now, we try dividing 202,426,757 by 3:
202,426,757 ÷ 3 = 67,475,585.6667
If the quotient is a whole number, then 3 and 67,475,585.6667 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 | 202,426,757 | |
| -1 | -202,426,757 |
Let's try dividing by 4:
202,426,757 ÷ 4 = 50,606,689.25
If the quotient is a whole number, then 4 and 50,606,689.25 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 | 202,426,757 | |
| -1 | 202,426,757 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 43 | 377 | 559 | 1,247 | 12,487 | 16,211 | 162,331 | 362,123 | 536,941 | 4,707,599 | 6,980,233 | 15,571,289 | 202,426,757 |
| -1 | -13 | -29 | -43 | -377 | -559 | -1,247 | -12,487 | -16,211 | -162,331 | -362,123 | -536,941 | -4,707,599 | -6,980,233 | -15,571,289 | -202,426,757 |
