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 200,054,545, 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 | 200,054,545 | |
| -1 | -200,054,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,054,545.
Example:
1 x 200,054,545 = 200,054,545
and
-1 x -200,054,545 = 200,054,545
Notice both answers equal 200,054,545
With that explanation out of the way, let's continue. Next, we take the number 200,054,545 and divide it by 2:
200,054,545 ÷ 2 = 100,027,272.5
If the quotient is a whole number, then 2 and 100,027,272.5 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 | 200,054,545 | |
| -1 | -200,054,545 |
Now, we try dividing 200,054,545 by 3:
200,054,545 ÷ 3 = 66,684,848.3333
If the quotient is a whole number, then 3 and 66,684,848.3333 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 | 200,054,545 | |
| -1 | -200,054,545 |
Let's try dividing by 4:
200,054,545 ÷ 4 = 50,013,636.25
If the quotient is a whole number, then 4 and 50,013,636.25 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 | 200,054,545 | |
| -1 | 200,054,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 295 | 359 | 1,795 | 1,889 | 9,445 | 21,181 | 105,905 | 111,451 | 557,255 | 678,151 | 3,390,755 | 40,010,909 | 200,054,545 |
| -1 | -5 | -59 | -295 | -359 | -1,795 | -1,889 | -9,445 | -21,181 | -105,905 | -111,451 | -557,255 | -678,151 | -3,390,755 | -40,010,909 | -200,054,545 |
