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 202,443,445, 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 | 202,443,445 | |
| -1 | -202,443,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,443,445.
Example:
1 x 202,443,445 = 202,443,445
and
-1 x -202,443,445 = 202,443,445
Notice both answers equal 202,443,445
With that explanation out of the way, let's continue. Next, we take the number 202,443,445 and divide it by 2:
202,443,445 ÷ 2 = 101,221,722.5
If the quotient is a whole number, then 2 and 101,221,722.5 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 | 202,443,445 | |
| -1 | -202,443,445 |
Now, we try dividing 202,443,445 by 3:
202,443,445 ÷ 3 = 67,481,148.3333
If the quotient is a whole number, then 3 and 67,481,148.3333 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 | 202,443,445 | |
| -1 | -202,443,445 |
Let's try dividing by 4:
202,443,445 ÷ 4 = 50,610,861.25
If the quotient is a whole number, then 4 and 50,610,861.25 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 | 202,443,445 | |
| -1 | 202,443,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 61 | 205 | 305 | 2,501 | 12,505 | 16,189 | 80,945 | 663,749 | 987,529 | 3,318,745 | 4,937,645 | 40,488,689 | 202,443,445 |
| -1 | -5 | -41 | -61 | -205 | -305 | -2,501 | -12,505 | -16,189 | -80,945 | -663,749 | -987,529 | -3,318,745 | -4,937,645 | -40,488,689 | -202,443,445 |
