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 177,161,735, 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 | 177,161,735 | |
| -1 | -177,161,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,161,735.
Example:
1 x 177,161,735 = 177,161,735
and
-1 x -177,161,735 = 177,161,735
Notice both answers equal 177,161,735
With that explanation out of the way, let's continue. Next, we take the number 177,161,735 and divide it by 2:
177,161,735 ÷ 2 = 88,580,867.5
If the quotient is a whole number, then 2 and 88,580,867.5 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 | 177,161,735 | |
| -1 | -177,161,735 |
Now, we try dividing 177,161,735 by 3:
177,161,735 ÷ 3 = 59,053,911.6667
If the quotient is a whole number, then 3 and 59,053,911.6667 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 | 177,161,735 | |
| -1 | -177,161,735 |
Let's try dividing by 4:
177,161,735 ÷ 4 = 44,290,433.75
If the quotient is a whole number, then 4 and 44,290,433.75 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 | 177,161,735 | |
| -1 | 177,161,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 67 | 185 | 335 | 2,479 | 12,395 | 14,293 | 71,465 | 528,841 | 957,631 | 2,644,205 | 4,788,155 | 35,432,347 | 177,161,735 |
| -1 | -5 | -37 | -67 | -185 | -335 | -2,479 | -12,395 | -14,293 | -71,465 | -528,841 | -957,631 | -2,644,205 | -4,788,155 | -35,432,347 | -177,161,735 |
