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 177,117,017, 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 | 177,117,017 | |
| -1 | -177,117,017 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,117,017.
Example:
1 x 177,117,017 = 177,117,017
and
-1 x -177,117,017 = 177,117,017
Notice both answers equal 177,117,017
With that explanation out of the way, let's continue. Next, we take the number 177,117,017 and divide it by 2:
177,117,017 ÷ 2 = 88,558,508.5
If the quotient is a whole number, then 2 and 88,558,508.5 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 | 177,117,017 | |
| -1 | -177,117,017 |
Now, we try dividing 177,117,017 by 3:
177,117,017 ÷ 3 = 59,039,005.6667
If the quotient is a whole number, then 3 and 59,039,005.6667 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 | 177,117,017 | |
| -1 | -177,117,017 |
Let's try dividing by 4:
177,117,017 ÷ 4 = 44,279,254.25
If the quotient is a whole number, then 4 and 44,279,254.25 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 | 177,117,017 | |
| -1 | 177,117,017 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 121 | 539 | 847 | 5,929 | 29,873 | 209,111 | 328,603 | 1,463,777 | 2,300,221 | 3,614,633 | 16,101,547 | 25,302,431 | 177,117,017 |
| -1 | -7 | -11 | -49 | -77 | -121 | -539 | -847 | -5,929 | -29,873 | -209,111 | -328,603 | -1,463,777 | -2,300,221 | -3,614,633 | -16,101,547 | -25,302,431 | -177,117,017 |
