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 252,075,847, 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 | 252,075,847 | |
| -1 | -252,075,847 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,075,847.
Example:
1 x 252,075,847 = 252,075,847
and
-1 x -252,075,847 = 252,075,847
Notice both answers equal 252,075,847
With that explanation out of the way, let's continue. Next, we take the number 252,075,847 and divide it by 2:
252,075,847 ÷ 2 = 126,037,923.5
If the quotient is a whole number, then 2 and 126,037,923.5 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 | 252,075,847 | |
| -1 | -252,075,847 |
Now, we try dividing 252,075,847 by 3:
252,075,847 ÷ 3 = 84,025,282.3333
If the quotient is a whole number, then 3 and 84,025,282.3333 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 | 252,075,847 | |
| -1 | -252,075,847 |
Let's try dividing by 4:
252,075,847 ÷ 4 = 63,018,961.75
If the quotient is a whole number, then 4 and 63,018,961.75 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 | 252,075,847 | |
| -1 | 252,075,847 |
If you did it right, you will end up with this table:
| 1 | 17 | 43 | 419 | 731 | 823 | 7,123 | 13,991 | 18,017 | 35,389 | 306,289 | 344,837 | 601,613 | 5,862,229 | 14,827,991 | 252,075,847 |
| -1 | -17 | -43 | -419 | -731 | -823 | -7,123 | -13,991 | -18,017 | -35,389 | -306,289 | -344,837 | -601,613 | -5,862,229 | -14,827,991 | -252,075,847 |
