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 108,035,213, 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 | 108,035,213 | |
| -1 | -108,035,213 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 108,035,213.
Example:
1 x 108,035,213 = 108,035,213
and
-1 x -108,035,213 = 108,035,213
Notice both answers equal 108,035,213
With that explanation out of the way, let's continue. Next, we take the number 108,035,213 and divide it by 2:
108,035,213 ÷ 2 = 54,017,606.5
If the quotient is a whole number, then 2 and 54,017,606.5 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 | 108,035,213 | |
| -1 | -108,035,213 |
Now, we try dividing 108,035,213 by 3:
108,035,213 ÷ 3 = 36,011,737.6667
If the quotient is a whole number, then 3 and 36,011,737.6667 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 | 108,035,213 | |
| -1 | -108,035,213 |
Let's try dividing by 4:
108,035,213 ÷ 4 = 27,008,803.25
If the quotient is a whole number, then 4 and 27,008,803.25 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 | 108,035,213 | |
| -1 | 108,035,213 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 121 | 143 | 173 | 397 | 1,573 | 1,903 | 2,249 | 4,367 | 5,161 | 20,933 | 24,739 | 48,037 | 56,771 | 68,681 | 272,129 | 624,481 | 755,491 | 892,853 | 8,310,401 | 9,821,383 | 108,035,213 |
| -1 | -11 | -13 | -121 | -143 | -173 | -397 | -1,573 | -1,903 | -2,249 | -4,367 | -5,161 | -20,933 | -24,739 | -48,037 | -56,771 | -68,681 | -272,129 | -624,481 | -755,491 | -892,853 | -8,310,401 | -9,821,383 | -108,035,213 |
