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 192,058,255, 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 | 192,058,255 | |
| -1 | -192,058,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 192,058,255.
Example:
1 x 192,058,255 = 192,058,255
and
-1 x -192,058,255 = 192,058,255
Notice both answers equal 192,058,255
With that explanation out of the way, let's continue. Next, we take the number 192,058,255 and divide it by 2:
192,058,255 ÷ 2 = 96,029,127.5
If the quotient is a whole number, then 2 and 96,029,127.5 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 | 192,058,255 | |
| -1 | -192,058,255 |
Now, we try dividing 192,058,255 by 3:
192,058,255 ÷ 3 = 64,019,418.3333
If the quotient is a whole number, then 3 and 64,019,418.3333 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 | 192,058,255 | |
| -1 | -192,058,255 |
Let's try dividing by 4:
192,058,255 ÷ 4 = 48,014,563.75
If the quotient is a whole number, then 4 and 48,014,563.75 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 | 192,058,255 | |
| -1 | 192,058,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 197 | 365 | 985 | 2,671 | 13,355 | 14,381 | 71,905 | 194,983 | 526,187 | 974,915 | 2,630,935 | 38,411,651 | 192,058,255 |
| -1 | -5 | -73 | -197 | -365 | -985 | -2,671 | -13,355 | -14,381 | -71,905 | -194,983 | -526,187 | -974,915 | -2,630,935 | -38,411,651 | -192,058,255 |
