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 97,967,903, 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 | 97,967,903 | |
| -1 | -97,967,903 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 97,967,903.
Example:
1 x 97,967,903 = 97,967,903
and
-1 x -97,967,903 = 97,967,903
Notice both answers equal 97,967,903
With that explanation out of the way, let's continue. Next, we take the number 97,967,903 and divide it by 2:
97,967,903 ÷ 2 = 48,983,951.5
If the quotient is a whole number, then 2 and 48,983,951.5 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 | 97,967,903 | |
| -1 | -97,967,903 |
Now, we try dividing 97,967,903 by 3:
97,967,903 ÷ 3 = 32,655,967.6667
If the quotient is a whole number, then 3 and 32,655,967.6667 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 | 97,967,903 | |
| -1 | -97,967,903 |
Let's try dividing by 4:
97,967,903 ÷ 4 = 24,491,975.75
If the quotient is a whole number, then 4 and 24,491,975.75 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 | 97,967,903 | |
| -1 | 97,967,903 |
If you did it right, you will end up with this table:
| 1 | 11 | 53 | 197 | 583 | 853 | 2,167 | 9,383 | 10,441 | 45,209 | 114,851 | 168,041 | 497,299 | 1,848,451 | 8,906,173 | 97,967,903 |
| -1 | -11 | -53 | -197 | -583 | -853 | -2,167 | -9,383 | -10,441 | -45,209 | -114,851 | -168,041 | -497,299 | -1,848,451 | -8,906,173 | -97,967,903 |
