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 200,650,705, 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 | 200,650,705 | |
| -1 | -200,650,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,650,705.
Example:
1 x 200,650,705 = 200,650,705
and
-1 x -200,650,705 = 200,650,705
Notice both answers equal 200,650,705
With that explanation out of the way, let's continue. Next, we take the number 200,650,705 and divide it by 2:
200,650,705 ÷ 2 = 100,325,352.5
If the quotient is a whole number, then 2 and 100,325,352.5 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 | 200,650,705 | |
| -1 | -200,650,705 |
Now, we try dividing 200,650,705 by 3:
200,650,705 ÷ 3 = 66,883,568.3333
If the quotient is a whole number, then 3 and 66,883,568.3333 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 | 200,650,705 | |
| -1 | -200,650,705 |
Let's try dividing by 4:
200,650,705 ÷ 4 = 50,162,676.25
If the quotient is a whole number, then 4 and 50,162,676.25 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 | 200,650,705 | |
| -1 | 200,650,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 199 | 421 | 479 | 995 | 2,105 | 2,395 | 83,779 | 95,321 | 201,659 | 418,895 | 476,605 | 1,008,295 | 40,130,141 | 200,650,705 |
| -1 | -5 | -199 | -421 | -479 | -995 | -2,105 | -2,395 | -83,779 | -95,321 | -201,659 | -418,895 | -476,605 | -1,008,295 | -40,130,141 | -200,650,705 |
