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 200,013,635, 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 | 200,013,635 | |
| -1 | -200,013,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,013,635.
Example:
1 x 200,013,635 = 200,013,635
and
-1 x -200,013,635 = 200,013,635
Notice both answers equal 200,013,635
With that explanation out of the way, let's continue. Next, we take the number 200,013,635 and divide it by 2:
200,013,635 ÷ 2 = 100,006,817.5
If the quotient is a whole number, then 2 and 100,006,817.5 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 | 200,013,635 | |
| -1 | -200,013,635 |
Now, we try dividing 200,013,635 by 3:
200,013,635 ÷ 3 = 66,671,211.6667
If the quotient is a whole number, then 3 and 66,671,211.6667 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 | 200,013,635 | |
| -1 | -200,013,635 |
Let's try dividing by 4:
200,013,635 ÷ 4 = 50,003,408.75
If the quotient is a whole number, then 4 and 50,003,408.75 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 | 200,013,635 | |
| -1 | 200,013,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 479 | 2,395 | 3,631 | 11,017 | 18,155 | 55,085 | 83,513 | 417,565 | 1,739,249 | 8,696,245 | 40,002,727 | 200,013,635 |
| -1 | -5 | -23 | -115 | -479 | -2,395 | -3,631 | -11,017 | -18,155 | -55,085 | -83,513 | -417,565 | -1,739,249 | -8,696,245 | -40,002,727 | -200,013,635 |
