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 403,722,755, 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 | 403,722,755 | |
| -1 | -403,722,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,722,755.
Example:
1 x 403,722,755 = 403,722,755
and
-1 x -403,722,755 = 403,722,755
Notice both answers equal 403,722,755
With that explanation out of the way, let's continue. Next, we take the number 403,722,755 and divide it by 2:
403,722,755 ÷ 2 = 201,861,377.5
If the quotient is a whole number, then 2 and 201,861,377.5 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 | 403,722,755 | |
| -1 | -403,722,755 |
Now, we try dividing 403,722,755 by 3:
403,722,755 ÷ 3 = 134,574,251.6667
If the quotient is a whole number, then 3 and 134,574,251.6667 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 | 403,722,755 | |
| -1 | -403,722,755 |
Let's try dividing by 4:
403,722,755 ÷ 4 = 100,930,688.75
If the quotient is a whole number, then 4 and 100,930,688.75 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 | 403,722,755 | |
| -1 | 403,722,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 101 | 479 | 505 | 1,669 | 2,395 | 8,345 | 48,379 | 168,569 | 241,895 | 799,451 | 842,845 | 3,997,255 | 80,744,551 | 403,722,755 |
| -1 | -5 | -101 | -479 | -505 | -1,669 | -2,395 | -8,345 | -48,379 | -168,569 | -241,895 | -799,451 | -842,845 | -3,997,255 | -80,744,551 | -403,722,755 |
