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 170,271,313, 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 | 170,271,313 | |
| -1 | -170,271,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 170,271,313.
Example:
1 x 170,271,313 = 170,271,313
and
-1 x -170,271,313 = 170,271,313
Notice both answers equal 170,271,313
With that explanation out of the way, let's continue. Next, we take the number 170,271,313 and divide it by 2:
170,271,313 ÷ 2 = 85,135,656.5
If the quotient is a whole number, then 2 and 85,135,656.5 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 | 170,271,313 | |
| -1 | -170,271,313 |
Now, we try dividing 170,271,313 by 3:
170,271,313 ÷ 3 = 56,757,104.3333
If the quotient is a whole number, then 3 and 56,757,104.3333 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 | 170,271,313 | |
| -1 | -170,271,313 |
Let's try dividing by 4:
170,271,313 ÷ 4 = 42,567,828.25
If the quotient is a whole number, then 4 and 42,567,828.25 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 | 170,271,313 | |
| -1 | 170,271,313 |
If you did it right, you will end up with this table:
| 1 | 31 | 61 | 127 | 709 | 1,891 | 3,937 | 7,747 | 21,979 | 43,249 | 90,043 | 240,157 | 1,340,719 | 2,791,333 | 5,492,623 | 170,271,313 |
| -1 | -31 | -61 | -127 | -709 | -1,891 | -3,937 | -7,747 | -21,979 | -43,249 | -90,043 | -240,157 | -1,340,719 | -2,791,333 | -5,492,623 | -170,271,313 |
