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 200,000,113, 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 | 200,000,113 | |
| -1 | -200,000,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,000,113.
Example:
1 x 200,000,113 = 200,000,113
and
-1 x -200,000,113 = 200,000,113
Notice both answers equal 200,000,113
With that explanation out of the way, let's continue. Next, we take the number 200,000,113 and divide it by 2:
200,000,113 ÷ 2 = 100,000,056.5
If the quotient is a whole number, then 2 and 100,000,056.5 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 | 200,000,113 | |
| -1 | -200,000,113 |
Now, we try dividing 200,000,113 by 3:
200,000,113 ÷ 3 = 66,666,704.3333
If the quotient is a whole number, then 3 and 66,666,704.3333 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 | 200,000,113 | |
| -1 | -200,000,113 |
Let's try dividing by 4:
200,000,113 ÷ 4 = 50,000,028.25
If the quotient is a whole number, then 4 and 50,000,028.25 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 | 200,000,113 | |
| -1 | 200,000,113 |
If you did it right, you will end up with this table:
| 1 | 71 | 79 | 181 | 197 | 5,609 | 12,851 | 13,987 | 14,299 | 15,563 | 35,657 | 1,015,229 | 1,104,973 | 2,531,647 | 2,816,903 | 200,000,113 |
| -1 | -71 | -79 | -181 | -197 | -5,609 | -12,851 | -13,987 | -14,299 | -15,563 | -35,657 | -1,015,229 | -1,104,973 | -2,531,647 | -2,816,903 | -200,000,113 |
