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 204,334,615, 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 | 204,334,615 | |
| -1 | -204,334,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,334,615.
Example:
1 x 204,334,615 = 204,334,615
and
-1 x -204,334,615 = 204,334,615
Notice both answers equal 204,334,615
With that explanation out of the way, let's continue. Next, we take the number 204,334,615 and divide it by 2:
204,334,615 ÷ 2 = 102,167,307.5
If the quotient is a whole number, then 2 and 102,167,307.5 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 | 204,334,615 | |
| -1 | -204,334,615 |
Now, we try dividing 204,334,615 by 3:
204,334,615 ÷ 3 = 68,111,538.3333
If the quotient is a whole number, then 3 and 68,111,538.3333 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 | 204,334,615 | |
| -1 | -204,334,615 |
Let's try dividing by 4:
204,334,615 ÷ 4 = 51,083,653.75
If the quotient is a whole number, then 4 and 51,083,653.75 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 | 204,334,615 | |
| -1 | 204,334,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 101 | 235 | 505 | 4,747 | 8,609 | 23,735 | 43,045 | 404,623 | 869,509 | 2,023,115 | 4,347,545 | 40,866,923 | 204,334,615 |
| -1 | -5 | -47 | -101 | -235 | -505 | -4,747 | -8,609 | -23,735 | -43,045 | -404,623 | -869,509 | -2,023,115 | -4,347,545 | -40,866,923 | -204,334,615 |
