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 531,822,865, 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 | 531,822,865 | |
| -1 | -531,822,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 531,822,865.
Example:
1 x 531,822,865 = 531,822,865
and
-1 x -531,822,865 = 531,822,865
Notice both answers equal 531,822,865
With that explanation out of the way, let's continue. Next, we take the number 531,822,865 and divide it by 2:
531,822,865 ÷ 2 = 265,911,432.5
If the quotient is a whole number, then 2 and 265,911,432.5 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 | 531,822,865 | |
| -1 | -531,822,865 |
Now, we try dividing 531,822,865 by 3:
531,822,865 ÷ 3 = 177,274,288.3333
If the quotient is a whole number, then 3 and 177,274,288.3333 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 | 531,822,865 | |
| -1 | -531,822,865 |
Let's try dividing by 4:
531,822,865 ÷ 4 = 132,955,716.25
If the quotient is a whole number, then 4 and 132,955,716.25 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 | 531,822,865 | |
| -1 | 531,822,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 79 | 395 | 553 | 2,765 | 192,341 | 961,705 | 1,346,387 | 6,731,935 | 15,194,939 | 75,974,695 | 106,364,573 | 531,822,865 |
| -1 | -5 | -7 | -35 | -79 | -395 | -553 | -2,765 | -192,341 | -961,705 | -1,346,387 | -6,731,935 | -15,194,939 | -75,974,695 | -106,364,573 | -531,822,865 |
