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 200,567,731, 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 | 200,567,731 | |
| -1 | -200,567,731 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,567,731.
Example:
1 x 200,567,731 = 200,567,731
and
-1 x -200,567,731 = 200,567,731
Notice both answers equal 200,567,731
With that explanation out of the way, let's continue. Next, we take the number 200,567,731 and divide it by 2:
200,567,731 ÷ 2 = 100,283,865.5
If the quotient is a whole number, then 2 and 100,283,865.5 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 | 200,567,731 | |
| -1 | -200,567,731 |
Now, we try dividing 200,567,731 by 3:
200,567,731 ÷ 3 = 66,855,910.3333
If the quotient is a whole number, then 3 and 66,855,910.3333 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 | 200,567,731 | |
| -1 | -200,567,731 |
Let's try dividing by 4:
200,567,731 ÷ 4 = 50,141,932.75
If the quotient is a whole number, then 4 and 50,141,932.75 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 | 200,567,731 | |
| -1 | 200,567,731 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 461 | 637 | 683 | 3,227 | 4,781 | 5,993 | 8,879 | 22,589 | 33,467 | 41,951 | 62,153 | 293,657 | 314,863 | 435,071 | 2,204,041 | 4,093,219 | 15,428,287 | 28,652,533 | 200,567,731 |
| -1 | -7 | -13 | -49 | -91 | -461 | -637 | -683 | -3,227 | -4,781 | -5,993 | -8,879 | -22,589 | -33,467 | -41,951 | -62,153 | -293,657 | -314,863 | -435,071 | -2,204,041 | -4,093,219 | -15,428,287 | -28,652,533 | -200,567,731 |
