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 563,534,405, 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 | 563,534,405 | |
| -1 | -563,534,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 563,534,405.
Example:
1 x 563,534,405 = 563,534,405
and
-1 x -563,534,405 = 563,534,405
Notice both answers equal 563,534,405
With that explanation out of the way, let's continue. Next, we take the number 563,534,405 and divide it by 2:
563,534,405 ÷ 2 = 281,767,202.5
If the quotient is a whole number, then 2 and 281,767,202.5 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 | 563,534,405 | |
| -1 | -563,534,405 |
Now, we try dividing 563,534,405 by 3:
563,534,405 ÷ 3 = 187,844,801.6667
If the quotient is a whole number, then 3 and 187,844,801.6667 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 | 563,534,405 | |
| -1 | -563,534,405 |
Let's try dividing by 4:
563,534,405 ÷ 4 = 140,883,601.25
If the quotient is a whole number, then 4 and 140,883,601.25 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 | 563,534,405 | |
| -1 | 563,534,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,093 | 5,465 | 7,651 | 14,731 | 38,255 | 73,655 | 103,117 | 515,585 | 16,100,983 | 80,504,915 | 112,706,881 | 563,534,405 |
| -1 | -5 | -7 | -35 | -1,093 | -5,465 | -7,651 | -14,731 | -38,255 | -73,655 | -103,117 | -515,585 | -16,100,983 | -80,504,915 | -112,706,881 | -563,534,405 |
