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 531,344,045, 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 | 531,344,045 | |
| -1 | -531,344,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 531,344,045.
Example:
1 x 531,344,045 = 531,344,045
and
-1 x -531,344,045 = 531,344,045
Notice both answers equal 531,344,045
With that explanation out of the way, let's continue. Next, we take the number 531,344,045 and divide it by 2:
531,344,045 ÷ 2 = 265,672,022.5
If the quotient is a whole number, then 2 and 265,672,022.5 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 | 531,344,045 | |
| -1 | -531,344,045 |
Now, we try dividing 531,344,045 by 3:
531,344,045 ÷ 3 = 177,114,681.6667
If the quotient is a whole number, then 3 and 177,114,681.6667 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 | 531,344,045 | |
| -1 | -531,344,045 |
Let's try dividing by 4:
531,344,045 ÷ 4 = 132,836,011.25
If the quotient is a whole number, then 4 and 132,836,011.25 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 | 531,344,045 | |
| -1 | 531,344,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 887 | 4,435 | 5,209 | 20,401 | 26,045 | 102,005 | 119,807 | 599,035 | 4,620,383 | 23,101,915 | 106,268,809 | 531,344,045 |
| -1 | -5 | -23 | -115 | -887 | -4,435 | -5,209 | -20,401 | -26,045 | -102,005 | -119,807 | -599,035 | -4,620,383 | -23,101,915 | -106,268,809 | -531,344,045 |
