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 75,223,997, 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 | 75,223,997 | |
| -1 | -75,223,997 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,223,997.
Example:
1 x 75,223,997 = 75,223,997
and
-1 x -75,223,997 = 75,223,997
Notice both answers equal 75,223,997
With that explanation out of the way, let's continue. Next, we take the number 75,223,997 and divide it by 2:
75,223,997 ÷ 2 = 37,611,998.5
If the quotient is a whole number, then 2 and 37,611,998.5 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 | 75,223,997 | |
| -1 | -75,223,997 |
Now, we try dividing 75,223,997 by 3:
75,223,997 ÷ 3 = 25,074,665.6667
If the quotient is a whole number, then 3 and 25,074,665.6667 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 | 75,223,997 | |
| -1 | -75,223,997 |
Let's try dividing by 4:
75,223,997 ÷ 4 = 18,805,999.25
If the quotient is a whole number, then 4 and 18,805,999.25 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 | 75,223,997 | |
| -1 | 75,223,997 |
If you did it right, you will end up with this table:
| 1 | 17 | 37 | 59 | 629 | 1,003 | 2,027 | 2,183 | 34,459 | 37,111 | 74,999 | 119,593 | 1,274,983 | 2,033,081 | 4,424,941 | 75,223,997 |
| -1 | -17 | -37 | -59 | -629 | -1,003 | -2,027 | -2,183 | -34,459 | -37,111 | -74,999 | -119,593 | -1,274,983 | -2,033,081 | -4,424,941 | -75,223,997 |
