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 200,004,545, 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 | 200,004,545 | |
| -1 | -200,004,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,004,545.
Example:
1 x 200,004,545 = 200,004,545
and
-1 x -200,004,545 = 200,004,545
Notice both answers equal 200,004,545
With that explanation out of the way, let's continue. Next, we take the number 200,004,545 and divide it by 2:
200,004,545 ÷ 2 = 100,002,272.5
If the quotient is a whole number, then 2 and 100,002,272.5 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 | 200,004,545 | |
| -1 | -200,004,545 |
Now, we try dividing 200,004,545 by 3:
200,004,545 ÷ 3 = 66,668,181.6667
If the quotient is a whole number, then 3 and 66,668,181.6667 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 | 200,004,545 | |
| -1 | -200,004,545 |
Let's try dividing by 4:
200,004,545 ÷ 4 = 50,001,136.25
If the quotient is a whole number, then 4 and 50,001,136.25 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 | 200,004,545 | |
| -1 | 200,004,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 161,947 | 809,735 | 2,105,311 | 3,076,993 | 10,526,555 | 15,384,965 | 40,000,909 | 200,004,545 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -161,947 | -809,735 | -2,105,311 | -3,076,993 | -10,526,555 | -15,384,965 | -40,000,909 | -200,004,545 |
