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 252,113,705, 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 | 252,113,705 | |
| -1 | -252,113,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,113,705.
Example:
1 x 252,113,705 = 252,113,705
and
-1 x -252,113,705 = 252,113,705
Notice both answers equal 252,113,705
With that explanation out of the way, let's continue. Next, we take the number 252,113,705 and divide it by 2:
252,113,705 ÷ 2 = 126,056,852.5
If the quotient is a whole number, then 2 and 126,056,852.5 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 | 252,113,705 | |
| -1 | -252,113,705 |
Now, we try dividing 252,113,705 by 3:
252,113,705 ÷ 3 = 84,037,901.6667
If the quotient is a whole number, then 3 and 84,037,901.6667 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 | 252,113,705 | |
| -1 | -252,113,705 |
Let's try dividing by 4:
252,113,705 ÷ 4 = 63,028,426.25
If the quotient is a whole number, then 4 and 63,028,426.25 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 | 252,113,705 | |
| -1 | 252,113,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 197 | 311 | 823 | 985 | 1,555 | 4,115 | 61,267 | 162,131 | 255,953 | 306,335 | 810,655 | 1,279,765 | 50,422,741 | 252,113,705 |
| -1 | -5 | -197 | -311 | -823 | -985 | -1,555 | -4,115 | -61,267 | -162,131 | -255,953 | -306,335 | -810,655 | -1,279,765 | -50,422,741 | -252,113,705 |
