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 170,207,675, 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 | 170,207,675 | |
| -1 | -170,207,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 170,207,675.
Example:
1 x 170,207,675 = 170,207,675
and
-1 x -170,207,675 = 170,207,675
Notice both answers equal 170,207,675
With that explanation out of the way, let's continue. Next, we take the number 170,207,675 and divide it by 2:
170,207,675 ÷ 2 = 85,103,837.5
If the quotient is a whole number, then 2 and 85,103,837.5 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 | 170,207,675 | |
| -1 | -170,207,675 |
Now, we try dividing 170,207,675 by 3:
170,207,675 ÷ 3 = 56,735,891.6667
If the quotient is a whole number, then 3 and 56,735,891.6667 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 | 170,207,675 | |
| -1 | -170,207,675 |
Let's try dividing by 4:
170,207,675 ÷ 4 = 42,551,918.75
If the quotient is a whole number, then 4 and 42,551,918.75 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 | 170,207,675 | |
| -1 | 170,207,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 121 | 275 | 605 | 3,025 | 56,267 | 281,335 | 618,937 | 1,406,675 | 3,094,685 | 6,808,307 | 15,473,425 | 34,041,535 | 170,207,675 |
| -1 | -5 | -11 | -25 | -55 | -121 | -275 | -605 | -3,025 | -56,267 | -281,335 | -618,937 | -1,406,675 | -3,094,685 | -6,808,307 | -15,473,425 | -34,041,535 | -170,207,675 |
