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 170,835,125, 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 | 170,835,125 | |
| -1 | -170,835,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 170,835,125.
Example:
1 x 170,835,125 = 170,835,125
and
-1 x -170,835,125 = 170,835,125
Notice both answers equal 170,835,125
With that explanation out of the way, let's continue. Next, we take the number 170,835,125 and divide it by 2:
170,835,125 ÷ 2 = 85,417,562.5
If the quotient is a whole number, then 2 and 85,417,562.5 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 | 170,835,125 | |
| -1 | -170,835,125 |
Now, we try dividing 170,835,125 by 3:
170,835,125 ÷ 3 = 56,945,041.6667
If the quotient is a whole number, then 3 and 56,945,041.6667 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 | 170,835,125 | |
| -1 | -170,835,125 |
Let's try dividing by 4:
170,835,125 ÷ 4 = 42,708,781.25
If the quotient is a whole number, then 4 and 42,708,781.25 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 | 170,835,125 | |
| -1 | 170,835,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 125 | 289 | 425 | 1,445 | 2,125 | 4,729 | 7,225 | 23,645 | 36,125 | 80,393 | 118,225 | 401,965 | 591,125 | 1,366,681 | 2,009,825 | 6,833,405 | 10,049,125 | 34,167,025 | 170,835,125 |
| -1 | -5 | -17 | -25 | -85 | -125 | -289 | -425 | -1,445 | -2,125 | -4,729 | -7,225 | -23,645 | -36,125 | -80,393 | -118,225 | -401,965 | -591,125 | -1,366,681 | -2,009,825 | -6,833,405 | -10,049,125 | -34,167,025 | -170,835,125 |
