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 97,745,477, 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 | 97,745,477 | |
| -1 | -97,745,477 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 97,745,477.
Example:
1 x 97,745,477 = 97,745,477
and
-1 x -97,745,477 = 97,745,477
Notice both answers equal 97,745,477
With that explanation out of the way, let's continue. Next, we take the number 97,745,477 and divide it by 2:
97,745,477 ÷ 2 = 48,872,738.5
If the quotient is a whole number, then 2 and 48,872,738.5 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 | 97,745,477 | |
| -1 | -97,745,477 |
Now, we try dividing 97,745,477 by 3:
97,745,477 ÷ 3 = 32,581,825.6667
If the quotient is a whole number, then 3 and 32,581,825.6667 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 | 97,745,477 | |
| -1 | -97,745,477 |
Let's try dividing by 4:
97,745,477 ÷ 4 = 24,436,369.25
If the quotient is a whole number, then 4 and 24,436,369.25 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 | 97,745,477 | |
| -1 | 97,745,477 |
If you did it right, you will end up with this table:
| 1 | 47 | 59 | 101 | 349 | 2,773 | 4,747 | 5,959 | 16,403 | 20,591 | 35,249 | 280,073 | 967,777 | 1,656,703 | 2,079,691 | 97,745,477 |
| -1 | -47 | -59 | -101 | -349 | -2,773 | -4,747 | -5,959 | -16,403 | -20,591 | -35,249 | -280,073 | -967,777 | -1,656,703 | -2,079,691 | -97,745,477 |
