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 536,644,121, 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 | 536,644,121 | |
| -1 | -536,644,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 536,644,121.
Example:
1 x 536,644,121 = 536,644,121
and
-1 x -536,644,121 = 536,644,121
Notice both answers equal 536,644,121
With that explanation out of the way, let's continue. Next, we take the number 536,644,121 and divide it by 2:
536,644,121 ÷ 2 = 268,322,060.5
If the quotient is a whole number, then 2 and 268,322,060.5 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 | 536,644,121 | |
| -1 | -536,644,121 |
Now, we try dividing 536,644,121 by 3:
536,644,121 ÷ 3 = 178,881,373.6667
If the quotient is a whole number, then 3 and 178,881,373.6667 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 | 536,644,121 | |
| -1 | -536,644,121 |
Let's try dividing by 4:
536,644,121 ÷ 4 = 134,161,030.25
If the quotient is a whole number, then 4 and 134,161,030.25 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 | 536,644,121 | |
| -1 | 536,644,121 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 169 | 533 | 1,681 | 1,889 | 6,929 | 21,853 | 24,557 | 77,449 | 284,089 | 319,241 | 1,006,837 | 3,175,409 | 13,088,881 | 41,280,317 | 536,644,121 |
| -1 | -13 | -41 | -169 | -533 | -1,681 | -1,889 | -6,929 | -21,853 | -24,557 | -77,449 | -284,089 | -319,241 | -1,006,837 | -3,175,409 | -13,088,881 | -41,280,317 | -536,644,121 |
