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 252,012,199, 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 | 252,012,199 | |
| -1 | -252,012,199 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,012,199.
Example:
1 x 252,012,199 = 252,012,199
and
-1 x -252,012,199 = 252,012,199
Notice both answers equal 252,012,199
With that explanation out of the way, let's continue. Next, we take the number 252,012,199 and divide it by 2:
252,012,199 ÷ 2 = 126,006,099.5
If the quotient is a whole number, then 2 and 126,006,099.5 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 | 252,012,199 | |
| -1 | -252,012,199 |
Now, we try dividing 252,012,199 by 3:
252,012,199 ÷ 3 = 84,004,066.3333
If the quotient is a whole number, then 3 and 84,004,066.3333 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 | 252,012,199 | |
| -1 | -252,012,199 |
Let's try dividing by 4:
252,012,199 ÷ 4 = 63,003,049.75
If the quotient is a whole number, then 4 and 63,003,049.75 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 | 252,012,199 | |
| -1 | 252,012,199 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 547 | 661 | 697 | 9,299 | 11,237 | 22,427 | 27,101 | 361,567 | 381,259 | 460,717 | 6,146,639 | 14,824,247 | 252,012,199 |
| -1 | -17 | -41 | -547 | -661 | -697 | -9,299 | -11,237 | -22,427 | -27,101 | -361,567 | -381,259 | -460,717 | -6,146,639 | -14,824,247 | -252,012,199 |
