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 531,734,621, 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 | 531,734,621 | |
| -1 | -531,734,621 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 531,734,621.
Example:
1 x 531,734,621 = 531,734,621
and
-1 x -531,734,621 = 531,734,621
Notice both answers equal 531,734,621
With that explanation out of the way, let's continue. Next, we take the number 531,734,621 and divide it by 2:
531,734,621 ÷ 2 = 265,867,310.5
If the quotient is a whole number, then 2 and 265,867,310.5 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 | 531,734,621 | |
| -1 | -531,734,621 |
Now, we try dividing 531,734,621 by 3:
531,734,621 ÷ 3 = 177,244,873.6667
If the quotient is a whole number, then 3 and 177,244,873.6667 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 | 531,734,621 | |
| -1 | -531,734,621 |
Let's try dividing by 4:
531,734,621 ÷ 4 = 132,933,655.25
If the quotient is a whole number, then 4 and 132,933,655.25 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 | 531,734,621 | |
| -1 | 531,734,621 |
If you did it right, you will end up with this table:
| 1 | 11 | 61 | 121 | 671 | 1,181 | 3,721 | 7,381 | 12,991 | 40,931 | 72,041 | 142,901 | 450,241 | 792,451 | 4,394,501 | 8,716,961 | 48,339,511 | 531,734,621 |
| -1 | -11 | -61 | -121 | -671 | -1,181 | -3,721 | -7,381 | -12,991 | -40,931 | -72,041 | -142,901 | -450,241 | -792,451 | -4,394,501 | -8,716,961 | -48,339,511 | -531,734,621 |
