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 564,356,155, 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 | 564,356,155 | |
| -1 | -564,356,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 564,356,155.
Example:
1 x 564,356,155 = 564,356,155
and
-1 x -564,356,155 = 564,356,155
Notice both answers equal 564,356,155
With that explanation out of the way, let's continue. Next, we take the number 564,356,155 and divide it by 2:
564,356,155 ÷ 2 = 282,178,077.5
If the quotient is a whole number, then 2 and 282,178,077.5 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 | 564,356,155 | |
| -1 | -564,356,155 |
Now, we try dividing 564,356,155 by 3:
564,356,155 ÷ 3 = 188,118,718.3333
If the quotient is a whole number, then 3 and 188,118,718.3333 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 | 564,356,155 | |
| -1 | -564,356,155 |
Let's try dividing by 4:
564,356,155 ÷ 4 = 141,089,038.75
If the quotient is a whole number, then 4 and 141,089,038.75 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 | 564,356,155 | |
| -1 | 564,356,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 457 | 2,285 | 5,027 | 22,453 | 25,135 | 112,265 | 246,983 | 1,234,915 | 10,261,021 | 51,305,105 | 112,871,231 | 564,356,155 |
| -1 | -5 | -11 | -55 | -457 | -2,285 | -5,027 | -22,453 | -25,135 | -112,265 | -246,983 | -1,234,915 | -10,261,021 | -51,305,105 | -112,871,231 | -564,356,155 |
