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 202,672,631, 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 | 202,672,631 | |
| -1 | -202,672,631 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,672,631.
Example:
1 x 202,672,631 = 202,672,631
and
-1 x -202,672,631 = 202,672,631
Notice both answers equal 202,672,631
With that explanation out of the way, let's continue. Next, we take the number 202,672,631 and divide it by 2:
202,672,631 ÷ 2 = 101,336,315.5
If the quotient is a whole number, then 2 and 101,336,315.5 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 | 202,672,631 | |
| -1 | -202,672,631 |
Now, we try dividing 202,672,631 by 3:
202,672,631 ÷ 3 = 67,557,543.6667
If the quotient is a whole number, then 3 and 67,557,543.6667 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 | 202,672,631 | |
| -1 | -202,672,631 |
Let's try dividing by 4:
202,672,631 ÷ 4 = 50,668,157.75
If the quotient is a whole number, then 4 and 50,668,157.75 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 | 202,672,631 | |
| -1 | 202,672,631 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 149 | 301 | 1,043 | 4,519 | 6,407 | 31,633 | 44,849 | 194,317 | 673,331 | 1,360,219 | 4,713,317 | 28,953,233 | 202,672,631 |
| -1 | -7 | -43 | -149 | -301 | -1,043 | -4,519 | -6,407 | -31,633 | -44,849 | -194,317 | -673,331 | -1,360,219 | -4,713,317 | -28,953,233 | -202,672,631 |
