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 403,135,501, 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 | 403,135,501 | |
| -1 | -403,135,501 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,135,501.
Example:
1 x 403,135,501 = 403,135,501
and
-1 x -403,135,501 = 403,135,501
Notice both answers equal 403,135,501
With that explanation out of the way, let's continue. Next, we take the number 403,135,501 and divide it by 2:
403,135,501 ÷ 2 = 201,567,750.5
If the quotient is a whole number, then 2 and 201,567,750.5 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 | 403,135,501 | |
| -1 | -403,135,501 |
Now, we try dividing 403,135,501 by 3:
403,135,501 ÷ 3 = 134,378,500.3333
If the quotient is a whole number, then 3 and 134,378,500.3333 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 | 403,135,501 | |
| -1 | -403,135,501 |
Let's try dividing by 4:
403,135,501 ÷ 4 = 100,783,875.25
If the quotient is a whole number, then 4 and 100,783,875.25 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 | 403,135,501 | |
| -1 | 403,135,501 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 479 | 527 | 1,597 | 8,143 | 14,849 | 27,149 | 49,507 | 252,433 | 764,963 | 841,619 | 13,004,371 | 23,713,853 | 403,135,501 |
| -1 | -17 | -31 | -479 | -527 | -1,597 | -8,143 | -14,849 | -27,149 | -49,507 | -252,433 | -764,963 | -841,619 | -13,004,371 | -23,713,853 | -403,135,501 |
