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 533,733,587, 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 | 533,733,587 | |
| -1 | -533,733,587 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 533,733,587.
Example:
1 x 533,733,587 = 533,733,587
and
-1 x -533,733,587 = 533,733,587
Notice both answers equal 533,733,587
With that explanation out of the way, let's continue. Next, we take the number 533,733,587 and divide it by 2:
533,733,587 ÷ 2 = 266,866,793.5
If the quotient is a whole number, then 2 and 266,866,793.5 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 | 533,733,587 | |
| -1 | -533,733,587 |
Now, we try dividing 533,733,587 by 3:
533,733,587 ÷ 3 = 177,911,195.6667
If the quotient is a whole number, then 3 and 177,911,195.6667 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 | 533,733,587 | |
| -1 | -533,733,587 |
Let's try dividing by 4:
533,733,587 ÷ 4 = 133,433,396.75
If the quotient is a whole number, then 4 and 133,433,396.75 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 | 533,733,587 | |
| -1 | 533,733,587 |
If you did it right, you will end up with this table:
| 1 | 43 | 73 | 193 | 881 | 3,139 | 8,299 | 14,089 | 37,883 | 64,313 | 170,033 | 605,827 | 2,765,459 | 7,311,419 | 12,412,409 | 533,733,587 |
| -1 | -43 | -73 | -193 | -881 | -3,139 | -8,299 | -14,089 | -37,883 | -64,313 | -170,033 | -605,827 | -2,765,459 | -7,311,419 | -12,412,409 | -533,733,587 |
