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 192,438,961, 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 | 192,438,961 | |
| -1 | -192,438,961 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 192,438,961.
Example:
1 x 192,438,961 = 192,438,961
and
-1 x -192,438,961 = 192,438,961
Notice both answers equal 192,438,961
With that explanation out of the way, let's continue. Next, we take the number 192,438,961 and divide it by 2:
192,438,961 ÷ 2 = 96,219,480.5
If the quotient is a whole number, then 2 and 96,219,480.5 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 | 192,438,961 | |
| -1 | -192,438,961 |
Now, we try dividing 192,438,961 by 3:
192,438,961 ÷ 3 = 64,146,320.3333
If the quotient is a whole number, then 3 and 64,146,320.3333 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 | 192,438,961 | |
| -1 | -192,438,961 |
Let's try dividing by 4:
192,438,961 ÷ 4 = 48,109,740.25
If the quotient is a whole number, then 4 and 48,109,740.25 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 | 192,438,961 | |
| -1 | 192,438,961 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 37 | 143 | 407 | 481 | 983 | 1,369 | 5,291 | 10,813 | 12,779 | 15,059 | 17,797 | 36,371 | 140,569 | 195,767 | 400,081 | 472,823 | 1,345,727 | 5,201,053 | 14,802,997 | 17,494,451 | 192,438,961 |
| -1 | -11 | -13 | -37 | -143 | -407 | -481 | -983 | -1,369 | -5,291 | -10,813 | -12,779 | -15,059 | -17,797 | -36,371 | -140,569 | -195,767 | -400,081 | -472,823 | -1,345,727 | -5,201,053 | -14,802,997 | -17,494,451 | -192,438,961 |
