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 252,418,325, 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 | 252,418,325 | |
| -1 | -252,418,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,418,325.
Example:
1 x 252,418,325 = 252,418,325
and
-1 x -252,418,325 = 252,418,325
Notice both answers equal 252,418,325
With that explanation out of the way, let's continue. Next, we take the number 252,418,325 and divide it by 2:
252,418,325 ÷ 2 = 126,209,162.5
If the quotient is a whole number, then 2 and 126,209,162.5 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 | 252,418,325 | |
| -1 | -252,418,325 |
Now, we try dividing 252,418,325 by 3:
252,418,325 ÷ 3 = 84,139,441.6667
If the quotient is a whole number, then 3 and 84,139,441.6667 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 | 252,418,325 | |
| -1 | -252,418,325 |
Let's try dividing by 4:
252,418,325 ÷ 4 = 63,104,581.25
If the quotient is a whole number, then 4 and 63,104,581.25 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 | 252,418,325 | |
| -1 | 252,418,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 227 | 475 | 1,135 | 2,341 | 4,313 | 5,675 | 11,705 | 21,565 | 44,479 | 58,525 | 107,825 | 222,395 | 531,407 | 1,111,975 | 2,657,035 | 10,096,733 | 13,285,175 | 50,483,665 | 252,418,325 |
| -1 | -5 | -19 | -25 | -95 | -227 | -475 | -1,135 | -2,341 | -4,313 | -5,675 | -11,705 | -21,565 | -44,479 | -58,525 | -107,825 | -222,395 | -531,407 | -1,111,975 | -2,657,035 | -10,096,733 | -13,285,175 | -50,483,665 | -252,418,325 |
