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 170,012,339, 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 | 170,012,339 | |
| -1 | -170,012,339 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 170,012,339.
Example:
1 x 170,012,339 = 170,012,339
and
-1 x -170,012,339 = 170,012,339
Notice both answers equal 170,012,339
With that explanation out of the way, let's continue. Next, we take the number 170,012,339 and divide it by 2:
170,012,339 ÷ 2 = 85,006,169.5
If the quotient is a whole number, then 2 and 85,006,169.5 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 | 170,012,339 | |
| -1 | -170,012,339 |
Now, we try dividing 170,012,339 by 3:
170,012,339 ÷ 3 = 56,670,779.6667
If the quotient is a whole number, then 3 and 56,670,779.6667 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 | 170,012,339 | |
| -1 | -170,012,339 |
Let's try dividing by 4:
170,012,339 ÷ 4 = 42,503,084.75
If the quotient is a whole number, then 4 and 42,503,084.75 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 | 170,012,339 | |
| -1 | 170,012,339 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 89 | 217 | 623 | 2,759 | 8,803 | 19,313 | 61,621 | 272,893 | 783,467 | 1,910,251 | 5,484,269 | 24,287,477 | 170,012,339 |
| -1 | -7 | -31 | -89 | -217 | -623 | -2,759 | -8,803 | -19,313 | -61,621 | -272,893 | -783,467 | -1,910,251 | -5,484,269 | -24,287,477 | -170,012,339 |
