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 202,061,447, 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 | 202,061,447 | |
| -1 | -202,061,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,061,447.
Example:
1 x 202,061,447 = 202,061,447
and
-1 x -202,061,447 = 202,061,447
Notice both answers equal 202,061,447
With that explanation out of the way, let's continue. Next, we take the number 202,061,447 and divide it by 2:
202,061,447 ÷ 2 = 101,030,723.5
If the quotient is a whole number, then 2 and 101,030,723.5 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 | 202,061,447 | |
| -1 | -202,061,447 |
Now, we try dividing 202,061,447 by 3:
202,061,447 ÷ 3 = 67,353,815.6667
If the quotient is a whole number, then 3 and 67,353,815.6667 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 | 202,061,447 | |
| -1 | -202,061,447 |
Let's try dividing by 4:
202,061,447 ÷ 4 = 50,515,361.75
If the quotient is a whole number, then 4 and 50,515,361.75 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 | 202,061,447 | |
| -1 | 202,061,447 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 49 | 133 | 361 | 931 | 2,527 | 11,423 | 17,689 | 79,961 | 217,037 | 559,727 | 1,519,259 | 4,123,703 | 10,634,813 | 28,865,921 | 202,061,447 |
| -1 | -7 | -19 | -49 | -133 | -361 | -931 | -2,527 | -11,423 | -17,689 | -79,961 | -217,037 | -559,727 | -1,519,259 | -4,123,703 | -10,634,813 | -28,865,921 | -202,061,447 |
