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 177,352,103, 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 | 177,352,103 | |
| -1 | -177,352,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,352,103.
Example:
1 x 177,352,103 = 177,352,103
and
-1 x -177,352,103 = 177,352,103
Notice both answers equal 177,352,103
With that explanation out of the way, let's continue. Next, we take the number 177,352,103 and divide it by 2:
177,352,103 ÷ 2 = 88,676,051.5
If the quotient is a whole number, then 2 and 88,676,051.5 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 | 177,352,103 | |
| -1 | -177,352,103 |
Now, we try dividing 177,352,103 by 3:
177,352,103 ÷ 3 = 59,117,367.6667
If the quotient is a whole number, then 3 and 59,117,367.6667 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 | 177,352,103 | |
| -1 | -177,352,103 |
Let's try dividing by 4:
177,352,103 ÷ 4 = 44,338,025.75
If the quotient is a whole number, then 4 and 44,338,025.75 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 | 177,352,103 | |
| -1 | 177,352,103 |
If you did it right, you will end up with this table:
| 1 | 23 | 47 | 359 | 457 | 1,081 | 8,257 | 10,511 | 16,873 | 21,479 | 164,063 | 388,079 | 494,017 | 3,773,449 | 7,710,961 | 177,352,103 |
| -1 | -23 | -47 | -359 | -457 | -1,081 | -8,257 | -10,511 | -16,873 | -21,479 | -164,063 | -388,079 | -494,017 | -3,773,449 | -7,710,961 | -177,352,103 |
