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 252,136,327, 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 | 252,136,327 | |
| -1 | -252,136,327 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,136,327.
Example:
1 x 252,136,327 = 252,136,327
and
-1 x -252,136,327 = 252,136,327
Notice both answers equal 252,136,327
With that explanation out of the way, let's continue. Next, we take the number 252,136,327 and divide it by 2:
252,136,327 ÷ 2 = 126,068,163.5
If the quotient is a whole number, then 2 and 126,068,163.5 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 | 252,136,327 | |
| -1 | -252,136,327 |
Now, we try dividing 252,136,327 by 3:
252,136,327 ÷ 3 = 84,045,442.3333
If the quotient is a whole number, then 3 and 84,045,442.3333 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 | 252,136,327 | |
| -1 | -252,136,327 |
Let's try dividing by 4:
252,136,327 ÷ 4 = 63,034,081.75
If the quotient is a whole number, then 4 and 63,034,081.75 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 | 252,136,327 | |
| -1 | 252,136,327 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 151 | 437 | 2,869 | 3,473 | 3,821 | 65,987 | 72,599 | 87,883 | 576,971 | 1,669,777 | 10,962,449 | 13,270,333 | 252,136,327 |
| -1 | -19 | -23 | -151 | -437 | -2,869 | -3,473 | -3,821 | -65,987 | -72,599 | -87,883 | -576,971 | -1,669,777 | -10,962,449 | -13,270,333 | -252,136,327 |
