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 175,175,099, 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 | 175,175,099 | |
| -1 | -175,175,099 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 175,175,099.
Example:
1 x 175,175,099 = 175,175,099
and
-1 x -175,175,099 = 175,175,099
Notice both answers equal 175,175,099
With that explanation out of the way, let's continue. Next, we take the number 175,175,099 and divide it by 2:
175,175,099 ÷ 2 = 87,587,549.5
If the quotient is a whole number, then 2 and 87,587,549.5 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 | 175,175,099 | |
| -1 | -175,175,099 |
Now, we try dividing 175,175,099 by 3:
175,175,099 ÷ 3 = 58,391,699.6667
If the quotient is a whole number, then 3 and 58,391,699.6667 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 | 175,175,099 | |
| -1 | -175,175,099 |
Let's try dividing by 4:
175,175,099 ÷ 4 = 43,793,774.75
If the quotient is a whole number, then 4 and 43,793,774.75 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 | 175,175,099 | |
| -1 | 175,175,099 |
If you did it right, you will end up with this table:
| 1 | 11 | 109 | 193 | 757 | 1,199 | 2,123 | 8,327 | 21,037 | 82,513 | 146,101 | 231,407 | 907,643 | 1,607,111 | 15,925,009 | 175,175,099 |
| -1 | -11 | -109 | -193 | -757 | -1,199 | -2,123 | -8,327 | -21,037 | -82,513 | -146,101 | -231,407 | -907,643 | -1,607,111 | -15,925,009 | -175,175,099 |
