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 187,058,179, 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 | 187,058,179 | |
| -1 | -187,058,179 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 187,058,179.
Example:
1 x 187,058,179 = 187,058,179
and
-1 x -187,058,179 = 187,058,179
Notice both answers equal 187,058,179
With that explanation out of the way, let's continue. Next, we take the number 187,058,179 and divide it by 2:
187,058,179 ÷ 2 = 93,529,089.5
If the quotient is a whole number, then 2 and 93,529,089.5 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 | 187,058,179 | |
| -1 | -187,058,179 |
Now, we try dividing 187,058,179 by 3:
187,058,179 ÷ 3 = 62,352,726.3333
If the quotient is a whole number, then 3 and 62,352,726.3333 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 | 187,058,179 | |
| -1 | -187,058,179 |
Let's try dividing by 4:
187,058,179 ÷ 4 = 46,764,544.75
If the quotient is a whole number, then 4 and 46,764,544.75 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 | 187,058,179 | |
| -1 | 187,058,179 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 83 | 581 | 913 | 6,391 | 29,269 | 204,883 | 321,959 | 2,253,713 | 2,429,327 | 17,005,289 | 26,722,597 | 187,058,179 |
| -1 | -7 | -11 | -77 | -83 | -581 | -913 | -6,391 | -29,269 | -204,883 | -321,959 | -2,253,713 | -2,429,327 | -17,005,289 | -26,722,597 | -187,058,179 |
