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 200,035,549, 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 | 200,035,549 | |
| -1 | -200,035,549 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,035,549.
Example:
1 x 200,035,549 = 200,035,549
and
-1 x -200,035,549 = 200,035,549
Notice both answers equal 200,035,549
With that explanation out of the way, let's continue. Next, we take the number 200,035,549 and divide it by 2:
200,035,549 ÷ 2 = 100,017,774.5
If the quotient is a whole number, then 2 and 100,017,774.5 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 | 200,035,549 | |
| -1 | -200,035,549 |
Now, we try dividing 200,035,549 by 3:
200,035,549 ÷ 3 = 66,678,516.3333
If the quotient is a whole number, then 3 and 66,678,516.3333 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 | 200,035,549 | |
| -1 | -200,035,549 |
Let's try dividing by 4:
200,035,549 ÷ 4 = 50,008,887.25
If the quotient is a whole number, then 4 and 50,008,887.25 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 | 200,035,549 | |
| -1 | 200,035,549 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 73 | 119 | 511 | 1,241 | 8,687 | 23,027 | 161,189 | 391,459 | 1,680,971 | 2,740,213 | 11,766,797 | 28,576,507 | 200,035,549 |
| -1 | -7 | -17 | -73 | -119 | -511 | -1,241 | -8,687 | -23,027 | -161,189 | -391,459 | -1,680,971 | -2,740,213 | -11,766,797 | -28,576,507 | -200,035,549 |
