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 253,682,875, 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 | 253,682,875 | |
| -1 | -253,682,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 253,682,875.
Example:
1 x 253,682,875 = 253,682,875
and
-1 x -253,682,875 = 253,682,875
Notice both answers equal 253,682,875
With that explanation out of the way, let's continue. Next, we take the number 253,682,875 and divide it by 2:
253,682,875 ÷ 2 = 126,841,437.5
If the quotient is a whole number, then 2 and 126,841,437.5 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 | 253,682,875 | |
| -1 | -253,682,875 |
Now, we try dividing 253,682,875 by 3:
253,682,875 ÷ 3 = 84,560,958.3333
If the quotient is a whole number, then 3 and 84,560,958.3333 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 | 253,682,875 | |
| -1 | -253,682,875 |
Let's try dividing by 4:
253,682,875 ÷ 4 = 63,420,718.75
If the quotient is a whole number, then 4 and 63,420,718.75 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 | 253,682,875 | |
| -1 | 253,682,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 173 | 865 | 4,325 | 11,731 | 21,625 | 58,655 | 293,275 | 1,466,375 | 2,029,463 | 10,147,315 | 50,736,575 | 253,682,875 |
| -1 | -5 | -25 | -125 | -173 | -865 | -4,325 | -11,731 | -21,625 | -58,655 | -293,275 | -1,466,375 | -2,029,463 | -10,147,315 | -50,736,575 | -253,682,875 |
