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 200,133,143, 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 | 200,133,143 | |
| -1 | -200,133,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,133,143.
Example:
1 x 200,133,143 = 200,133,143
and
-1 x -200,133,143 = 200,133,143
Notice both answers equal 200,133,143
With that explanation out of the way, let's continue. Next, we take the number 200,133,143 and divide it by 2:
200,133,143 ÷ 2 = 100,066,571.5
If the quotient is a whole number, then 2 and 100,066,571.5 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 | 200,133,143 | |
| -1 | -200,133,143 |
Now, we try dividing 200,133,143 by 3:
200,133,143 ÷ 3 = 66,711,047.6667
If the quotient is a whole number, then 3 and 66,711,047.6667 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 | 200,133,143 | |
| -1 | -200,133,143 |
Let's try dividing by 4:
200,133,143 ÷ 4 = 50,033,285.75
If the quotient is a whole number, then 4 and 50,033,285.75 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 | 200,133,143 | |
| -1 | 200,133,143 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 89 | 161 | 623 | 2,047 | 13,967 | 14,329 | 97,769 | 321,241 | 1,243,063 | 2,248,687 | 8,701,441 | 28,590,449 | 200,133,143 |
| -1 | -7 | -23 | -89 | -161 | -623 | -2,047 | -13,967 | -14,329 | -97,769 | -321,241 | -1,243,063 | -2,248,687 | -8,701,441 | -28,590,449 | -200,133,143 |
