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 465,450,205, 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 | 465,450,205 | |
| -1 | -465,450,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 465,450,205.
Example:
1 x 465,450,205 = 465,450,205
and
-1 x -465,450,205 = 465,450,205
Notice both answers equal 465,450,205
With that explanation out of the way, let's continue. Next, we take the number 465,450,205 and divide it by 2:
465,450,205 ÷ 2 = 232,725,102.5
If the quotient is a whole number, then 2 and 232,725,102.5 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 | 465,450,205 | |
| -1 | -465,450,205 |
Now, we try dividing 465,450,205 by 3:
465,450,205 ÷ 3 = 155,150,068.3333
If the quotient is a whole number, then 3 and 155,150,068.3333 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 | 465,450,205 | |
| -1 | -465,450,205 |
Let's try dividing by 4:
465,450,205 ÷ 4 = 116,362,551.25
If the quotient is a whole number, then 4 and 116,362,551.25 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 | 465,450,205 | |
| -1 | 465,450,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 131 | 655 | 1,441 | 7,205 | 64,601 | 323,005 | 710,611 | 3,553,055 | 8,462,731 | 42,313,655 | 93,090,041 | 465,450,205 |
| -1 | -5 | -11 | -55 | -131 | -655 | -1,441 | -7,205 | -64,601 | -323,005 | -710,611 | -3,553,055 | -8,462,731 | -42,313,655 | -93,090,041 | -465,450,205 |
