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 175,507,645, 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 | 175,507,645 | |
| -1 | -175,507,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 175,507,645.
Example:
1 x 175,507,645 = 175,507,645
and
-1 x -175,507,645 = 175,507,645
Notice both answers equal 175,507,645
With that explanation out of the way, let's continue. Next, we take the number 175,507,645 and divide it by 2:
175,507,645 ÷ 2 = 87,753,822.5
If the quotient is a whole number, then 2 and 87,753,822.5 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 | 175,507,645 | |
| -1 | -175,507,645 |
Now, we try dividing 175,507,645 by 3:
175,507,645 ÷ 3 = 58,502,548.3333
If the quotient is a whole number, then 3 and 58,502,548.3333 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 | 175,507,645 | |
| -1 | -175,507,645 |
Let's try dividing by 4:
175,507,645 ÷ 4 = 43,876,911.25
If the quotient is a whole number, then 4 and 43,876,911.25 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 | 175,507,645 | |
| -1 | 175,507,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 113 | 265 | 565 | 5,861 | 5,989 | 29,305 | 29,945 | 310,633 | 662,293 | 1,553,165 | 3,311,465 | 35,101,529 | 175,507,645 |
| -1 | -5 | -53 | -113 | -265 | -565 | -5,861 | -5,989 | -29,305 | -29,945 | -310,633 | -662,293 | -1,553,165 | -3,311,465 | -35,101,529 | -175,507,645 |
