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 252,231,553, 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 | 252,231,553 | |
| -1 | -252,231,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,231,553.
Example:
1 x 252,231,553 = 252,231,553
and
-1 x -252,231,553 = 252,231,553
Notice both answers equal 252,231,553
With that explanation out of the way, let's continue. Next, we take the number 252,231,553 and divide it by 2:
252,231,553 ÷ 2 = 126,115,776.5
If the quotient is a whole number, then 2 and 126,115,776.5 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 | 252,231,553 | |
| -1 | -252,231,553 |
Now, we try dividing 252,231,553 by 3:
252,231,553 ÷ 3 = 84,077,184.3333
If the quotient is a whole number, then 3 and 84,077,184.3333 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 | 252,231,553 | |
| -1 | -252,231,553 |
Let's try dividing by 4:
252,231,553 ÷ 4 = 63,057,888.25
If the quotient is a whole number, then 4 and 63,057,888.25 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 | 252,231,553 | |
| -1 | 252,231,553 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 259 | 457 | 2,131 | 3,199 | 14,917 | 16,909 | 78,847 | 118,363 | 551,929 | 973,867 | 6,817,069 | 36,033,079 | 252,231,553 |
| -1 | -7 | -37 | -259 | -457 | -2,131 | -3,199 | -14,917 | -16,909 | -78,847 | -118,363 | -551,929 | -973,867 | -6,817,069 | -36,033,079 | -252,231,553 |
