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 531,035,465, 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 | 531,035,465 | |
| -1 | -531,035,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 531,035,465.
Example:
1 x 531,035,465 = 531,035,465
and
-1 x -531,035,465 = 531,035,465
Notice both answers equal 531,035,465
With that explanation out of the way, let's continue. Next, we take the number 531,035,465 and divide it by 2:
531,035,465 ÷ 2 = 265,517,732.5
If the quotient is a whole number, then 2 and 265,517,732.5 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 | 531,035,465 | |
| -1 | -531,035,465 |
Now, we try dividing 531,035,465 by 3:
531,035,465 ÷ 3 = 177,011,821.6667
If the quotient is a whole number, then 3 and 177,011,821.6667 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 | 531,035,465 | |
| -1 | -531,035,465 |
Let's try dividing by 4:
531,035,465 ÷ 4 = 132,758,866.25
If the quotient is a whole number, then 4 and 132,758,866.25 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 | 531,035,465 | |
| -1 | 531,035,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 109 | 545 | 2,071 | 10,355 | 51,283 | 256,415 | 974,377 | 4,871,885 | 5,589,847 | 27,949,235 | 106,207,093 | 531,035,465 |
| -1 | -5 | -19 | -95 | -109 | -545 | -2,071 | -10,355 | -51,283 | -256,415 | -974,377 | -4,871,885 | -5,589,847 | -27,949,235 | -106,207,093 | -531,035,465 |
