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 177,121,375, 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 | 177,121,375 | |
| -1 | -177,121,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,121,375.
Example:
1 x 177,121,375 = 177,121,375
and
-1 x -177,121,375 = 177,121,375
Notice both answers equal 177,121,375
With that explanation out of the way, let's continue. Next, we take the number 177,121,375 and divide it by 2:
177,121,375 ÷ 2 = 88,560,687.5
If the quotient is a whole number, then 2 and 88,560,687.5 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 | 177,121,375 | |
| -1 | -177,121,375 |
Now, we try dividing 177,121,375 by 3:
177,121,375 ÷ 3 = 59,040,458.3333
If the quotient is a whole number, then 3 and 59,040,458.3333 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 | 177,121,375 | |
| -1 | -177,121,375 |
Let's try dividing by 4:
177,121,375 ÷ 4 = 44,280,343.75
If the quotient is a whole number, then 4 and 44,280,343.75 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 | 177,121,375 | |
| -1 | 177,121,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 103 | 125 | 515 | 2,575 | 12,875 | 13,757 | 68,785 | 343,925 | 1,416,971 | 1,719,625 | 7,084,855 | 35,424,275 | 177,121,375 |
| -1 | -5 | -25 | -103 | -125 | -515 | -2,575 | -12,875 | -13,757 | -68,785 | -343,925 | -1,416,971 | -1,719,625 | -7,084,855 | -35,424,275 | -177,121,375 |
