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 202,672,645, 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 | 202,672,645 | |
| -1 | -202,672,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,672,645.
Example:
1 x 202,672,645 = 202,672,645
and
-1 x -202,672,645 = 202,672,645
Notice both answers equal 202,672,645
With that explanation out of the way, let's continue. Next, we take the number 202,672,645 and divide it by 2:
202,672,645 ÷ 2 = 101,336,322.5
If the quotient is a whole number, then 2 and 101,336,322.5 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 | 202,672,645 | |
| -1 | -202,672,645 |
Now, we try dividing 202,672,645 by 3:
202,672,645 ÷ 3 = 67,557,548.3333
If the quotient is a whole number, then 3 and 67,557,548.3333 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 | 202,672,645 | |
| -1 | -202,672,645 |
Let's try dividing by 4:
202,672,645 ÷ 4 = 50,668,161.25
If the quotient is a whole number, then 4 and 50,668,161.25 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 | 202,672,645 | |
| -1 | 202,672,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 457 | 2,285 | 3,199 | 12,671 | 15,995 | 63,355 | 88,697 | 443,485 | 5,790,647 | 28,953,235 | 40,534,529 | 202,672,645 |
| -1 | -5 | -7 | -35 | -457 | -2,285 | -3,199 | -12,671 | -15,995 | -63,355 | -88,697 | -443,485 | -5,790,647 | -28,953,235 | -40,534,529 | -202,672,645 |
