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 177,574,705, 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 | 177,574,705 | |
| -1 | -177,574,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 177,574,705.
Example:
1 x 177,574,705 = 177,574,705
and
-1 x -177,574,705 = 177,574,705
Notice both answers equal 177,574,705
With that explanation out of the way, let's continue. Next, we take the number 177,574,705 and divide it by 2:
177,574,705 ÷ 2 = 88,787,352.5
If the quotient is a whole number, then 2 and 88,787,352.5 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 | 177,574,705 | |
| -1 | -177,574,705 |
Now, we try dividing 177,574,705 by 3:
177,574,705 ÷ 3 = 59,191,568.3333
If the quotient is a whole number, then 3 and 59,191,568.3333 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 | 177,574,705 | |
| -1 | -177,574,705 |
Let's try dividing by 4:
177,574,705 ÷ 4 = 44,393,676.25
If the quotient is a whole number, then 4 and 44,393,676.25 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 | 177,574,705 | |
| -1 | 177,574,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 461,233 | 2,306,165 | 3,228,631 | 5,073,563 | 16,143,155 | 25,367,815 | 35,514,941 | 177,574,705 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -461,233 | -2,306,165 | -3,228,631 | -5,073,563 | -16,143,155 | -25,367,815 | -35,514,941 | -177,574,705 |
