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 188,056,375, 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 | 188,056,375 | |
| -1 | -188,056,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 188,056,375.
Example:
1 x 188,056,375 = 188,056,375
and
-1 x -188,056,375 = 188,056,375
Notice both answers equal 188,056,375
With that explanation out of the way, let's continue. Next, we take the number 188,056,375 and divide it by 2:
188,056,375 ÷ 2 = 94,028,187.5
If the quotient is a whole number, then 2 and 94,028,187.5 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 | 188,056,375 | |
| -1 | -188,056,375 |
Now, we try dividing 188,056,375 by 3:
188,056,375 ÷ 3 = 62,685,458.3333
If the quotient is a whole number, then 3 and 62,685,458.3333 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 | 188,056,375 | |
| -1 | -188,056,375 |
Let's try dividing by 4:
188,056,375 ÷ 4 = 47,014,093.75
If the quotient is a whole number, then 4 and 47,014,093.75 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 | 188,056,375 | |
| -1 | 188,056,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 1,625 | 115,727 | 578,635 | 1,504,451 | 2,893,175 | 7,522,255 | 14,465,875 | 37,611,275 | 188,056,375 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -1,625 | -115,727 | -578,635 | -1,504,451 | -2,893,175 | -7,522,255 | -14,465,875 | -37,611,275 | -188,056,375 |
