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 403,130,255, 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 | 403,130,255 | |
| -1 | -403,130,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,130,255.
Example:
1 x 403,130,255 = 403,130,255
and
-1 x -403,130,255 = 403,130,255
Notice both answers equal 403,130,255
With that explanation out of the way, let's continue. Next, we take the number 403,130,255 and divide it by 2:
403,130,255 ÷ 2 = 201,565,127.5
If the quotient is a whole number, then 2 and 201,565,127.5 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 | 403,130,255 | |
| -1 | -403,130,255 |
Now, we try dividing 403,130,255 by 3:
403,130,255 ÷ 3 = 134,376,751.6667
If the quotient is a whole number, then 3 and 134,376,751.6667 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 | 403,130,255 | |
| -1 | -403,130,255 |
Let's try dividing by 4:
403,130,255 ÷ 4 = 100,782,563.75
If the quotient is a whole number, then 4 and 100,782,563.75 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 | 403,130,255 | |
| -1 | 403,130,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 121 | 605 | 613 | 1,087 | 3,065 | 5,435 | 6,743 | 11,957 | 33,715 | 59,785 | 74,173 | 131,527 | 370,865 | 657,635 | 666,331 | 3,331,655 | 7,329,641 | 36,648,205 | 80,626,051 | 403,130,255 |
| -1 | -5 | -11 | -55 | -121 | -605 | -613 | -1,087 | -3,065 | -5,435 | -6,743 | -11,957 | -33,715 | -59,785 | -74,173 | -131,527 | -370,865 | -657,635 | -666,331 | -3,331,655 | -7,329,641 | -36,648,205 | -80,626,051 | -403,130,255 |
