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 175,372,115, 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 | 175,372,115 | |
| -1 | -175,372,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 175,372,115.
Example:
1 x 175,372,115 = 175,372,115
and
-1 x -175,372,115 = 175,372,115
Notice both answers equal 175,372,115
With that explanation out of the way, let's continue. Next, we take the number 175,372,115 and divide it by 2:
175,372,115 ÷ 2 = 87,686,057.5
If the quotient is a whole number, then 2 and 87,686,057.5 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 | 175,372,115 | |
| -1 | -175,372,115 |
Now, we try dividing 175,372,115 by 3:
175,372,115 ÷ 3 = 58,457,371.6667
If the quotient is a whole number, then 3 and 58,457,371.6667 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 | 175,372,115 | |
| -1 | -175,372,115 |
Let's try dividing by 4:
175,372,115 ÷ 4 = 43,843,028.75
If the quotient is a whole number, then 4 and 43,843,028.75 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 | 175,372,115 | |
| -1 | 175,372,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 983 | 1,151 | 4,915 | 5,755 | 30,473 | 35,681 | 152,365 | 178,405 | 1,131,433 | 5,657,165 | 35,074,423 | 175,372,115 |
| -1 | -5 | -31 | -155 | -983 | -1,151 | -4,915 | -5,755 | -30,473 | -35,681 | -152,365 | -178,405 | -1,131,433 | -5,657,165 | -35,074,423 | -175,372,115 |
