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 192,736,625, 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 | 192,736,625 | |
| -1 | -192,736,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 192,736,625.
Example:
1 x 192,736,625 = 192,736,625
and
-1 x -192,736,625 = 192,736,625
Notice both answers equal 192,736,625
With that explanation out of the way, let's continue. Next, we take the number 192,736,625 and divide it by 2:
192,736,625 ÷ 2 = 96,368,312.5
If the quotient is a whole number, then 2 and 96,368,312.5 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 | 192,736,625 | |
| -1 | -192,736,625 |
Now, we try dividing 192,736,625 by 3:
192,736,625 ÷ 3 = 64,245,541.6667
If the quotient is a whole number, then 3 and 64,245,541.6667 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 | 192,736,625 | |
| -1 | -192,736,625 |
Let's try dividing by 4:
192,736,625 ÷ 4 = 48,184,156.25
If the quotient is a whole number, then 4 and 48,184,156.25 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 | 192,736,625 | |
| -1 | 192,736,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 251 | 1,255 | 6,143 | 6,275 | 30,715 | 31,375 | 153,575 | 767,875 | 1,541,893 | 7,709,465 | 38,547,325 | 192,736,625 |
| -1 | -5 | -25 | -125 | -251 | -1,255 | -6,143 | -6,275 | -30,715 | -31,375 | -153,575 | -767,875 | -1,541,893 | -7,709,465 | -38,547,325 | -192,736,625 |
