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 252,426,839, 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 | 252,426,839 | |
| -1 | -252,426,839 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,426,839.
Example:
1 x 252,426,839 = 252,426,839
and
-1 x -252,426,839 = 252,426,839
Notice both answers equal 252,426,839
With that explanation out of the way, let's continue. Next, we take the number 252,426,839 and divide it by 2:
252,426,839 ÷ 2 = 126,213,419.5
If the quotient is a whole number, then 2 and 126,213,419.5 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 | 252,426,839 | |
| -1 | -252,426,839 |
Now, we try dividing 252,426,839 by 3:
252,426,839 ÷ 3 = 84,142,279.6667
If the quotient is a whole number, then 3 and 84,142,279.6667 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 | 252,426,839 | |
| -1 | -252,426,839 |
Let's try dividing by 4:
252,426,839 ÷ 4 = 63,106,709.75
If the quotient is a whole number, then 4 and 63,106,709.75 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 | 252,426,839 | |
| -1 | 252,426,839 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 59 | 259 | 413 | 2,183 | 15,281 | 16,519 | 115,633 | 611,203 | 974,621 | 4,278,421 | 6,822,347 | 36,060,977 | 252,426,839 |
| -1 | -7 | -37 | -59 | -259 | -413 | -2,183 | -15,281 | -16,519 | -115,633 | -611,203 | -974,621 | -4,278,421 | -6,822,347 | -36,060,977 | -252,426,839 |
