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 100,847,345, 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 | 100,847,345 | |
| -1 | -100,847,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,847,345.
Example:
1 x 100,847,345 = 100,847,345
and
-1 x -100,847,345 = 100,847,345
Notice both answers equal 100,847,345
With that explanation out of the way, let's continue. Next, we take the number 100,847,345 and divide it by 2:
100,847,345 ÷ 2 = 50,423,672.5
If the quotient is a whole number, then 2 and 50,423,672.5 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 | 100,847,345 | |
| -1 | -100,847,345 |
Now, we try dividing 100,847,345 by 3:
100,847,345 ÷ 3 = 33,615,781.6667
If the quotient is a whole number, then 3 and 33,615,781.6667 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 | 100,847,345 | |
| -1 | -100,847,345 |
Let's try dividing by 4:
100,847,345 ÷ 4 = 25,211,836.25
If the quotient is a whole number, then 4 and 25,211,836.25 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 | 100,847,345 | |
| -1 | 100,847,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 109 | 545 | 2,071 | 9,739 | 10,355 | 48,695 | 185,041 | 925,205 | 1,061,551 | 5,307,755 | 20,169,469 | 100,847,345 |
| -1 | -5 | -19 | -95 | -109 | -545 | -2,071 | -9,739 | -10,355 | -48,695 | -185,041 | -925,205 | -1,061,551 | -5,307,755 | -20,169,469 | -100,847,345 |
