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 531,141,445, 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 | 531,141,445 | |
| -1 | -531,141,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 531,141,445.
Example:
1 x 531,141,445 = 531,141,445
and
-1 x -531,141,445 = 531,141,445
Notice both answers equal 531,141,445
With that explanation out of the way, let's continue. Next, we take the number 531,141,445 and divide it by 2:
531,141,445 ÷ 2 = 265,570,722.5
If the quotient is a whole number, then 2 and 265,570,722.5 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 | 531,141,445 | |
| -1 | -531,141,445 |
Now, we try dividing 531,141,445 by 3:
531,141,445 ÷ 3 = 177,047,148.3333
If the quotient is a whole number, then 3 and 177,047,148.3333 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 | 531,141,445 | |
| -1 | -531,141,445 |
Let's try dividing by 4:
531,141,445 ÷ 4 = 132,785,361.25
If the quotient is a whole number, then 4 and 132,785,361.25 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 | 531,141,445 | |
| -1 | 531,141,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 97 | 155 | 485 | 3,007 | 15,035 | 35,327 | 176,635 | 1,095,137 | 3,426,719 | 5,475,685 | 17,133,595 | 106,228,289 | 531,141,445 |
| -1 | -5 | -31 | -97 | -155 | -485 | -3,007 | -15,035 | -35,327 | -176,635 | -1,095,137 | -3,426,719 | -5,475,685 | -17,133,595 | -106,228,289 | -531,141,445 |
