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 171,710,201, 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 | 171,710,201 | |
| -1 | -171,710,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 171,710,201.
Example:
1 x 171,710,201 = 171,710,201
and
-1 x -171,710,201 = 171,710,201
Notice both answers equal 171,710,201
With that explanation out of the way, let's continue. Next, we take the number 171,710,201 and divide it by 2:
171,710,201 ÷ 2 = 85,855,100.5
If the quotient is a whole number, then 2 and 85,855,100.5 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 | 171,710,201 | |
| -1 | -171,710,201 |
Now, we try dividing 171,710,201 by 3:
171,710,201 ÷ 3 = 57,236,733.6667
If the quotient is a whole number, then 3 and 57,236,733.6667 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 | 171,710,201 | |
| -1 | -171,710,201 |
Let's try dividing by 4:
171,710,201 ÷ 4 = 42,927,550.25
If the quotient is a whole number, then 4 and 42,927,550.25 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 | 171,710,201 | |
| -1 | 171,710,201 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 101 | 247 | 1,313 | 1,919 | 6,883 | 24,947 | 89,479 | 130,777 | 695,183 | 1,700,101 | 9,037,379 | 13,208,477 | 171,710,201 |
| -1 | -13 | -19 | -101 | -247 | -1,313 | -1,919 | -6,883 | -24,947 | -89,479 | -130,777 | -695,183 | -1,700,101 | -9,037,379 | -13,208,477 | -171,710,201 |
