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 100,003,079, 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 | 100,003,079 | |
| -1 | -100,003,079 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,003,079.
Example:
1 x 100,003,079 = 100,003,079
and
-1 x -100,003,079 = 100,003,079
Notice both answers equal 100,003,079
With that explanation out of the way, let's continue. Next, we take the number 100,003,079 and divide it by 2:
100,003,079 ÷ 2 = 50,001,539.5
If the quotient is a whole number, then 2 and 50,001,539.5 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 | 100,003,079 | |
| -1 | -100,003,079 |
Now, we try dividing 100,003,079 by 3:
100,003,079 ÷ 3 = 33,334,359.6667
If the quotient is a whole number, then 3 and 33,334,359.6667 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 | 100,003,079 | |
| -1 | -100,003,079 |
Let's try dividing by 4:
100,003,079 ÷ 4 = 25,000,769.75
If the quotient is a whole number, then 4 and 25,000,769.75 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 | 100,003,079 | |
| -1 | 100,003,079 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 113 | 473 | 1,243 | 1,871 | 4,859 | 20,581 | 53,449 | 80,453 | 211,423 | 884,983 | 2,325,653 | 9,091,189 | 100,003,079 |
| -1 | -11 | -43 | -113 | -473 | -1,243 | -1,871 | -4,859 | -20,581 | -53,449 | -80,453 | -211,423 | -884,983 | -2,325,653 | -9,091,189 | -100,003,079 |
