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 163,234,417, 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 | 163,234,417 | |
| -1 | -163,234,417 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 163,234,417.
Example:
1 x 163,234,417 = 163,234,417
and
-1 x -163,234,417 = 163,234,417
Notice both answers equal 163,234,417
With that explanation out of the way, let's continue. Next, we take the number 163,234,417 and divide it by 2:
163,234,417 ÷ 2 = 81,617,208.5
If the quotient is a whole number, then 2 and 81,617,208.5 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 | 163,234,417 | |
| -1 | -163,234,417 |
Now, we try dividing 163,234,417 by 3:
163,234,417 ÷ 3 = 54,411,472.3333
If the quotient is a whole number, then 3 and 54,411,472.3333 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 | 163,234,417 | |
| -1 | -163,234,417 |
Let's try dividing by 4:
163,234,417 ÷ 4 = 40,808,604.25
If the quotient is a whole number, then 4 and 40,808,604.25 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 | 163,234,417 | |
| -1 | 163,234,417 |
If you did it right, you will end up with this table:
| 1 | 29 | 37 | 149 | 1,021 | 1,073 | 4,321 | 5,513 | 29,609 | 37,777 | 152,129 | 159,877 | 1,095,533 | 4,411,741 | 5,628,773 | 163,234,417 |
| -1 | -29 | -37 | -149 | -1,021 | -1,073 | -4,321 | -5,513 | -29,609 | -37,777 | -152,129 | -159,877 | -1,095,533 | -4,411,741 | -5,628,773 | -163,234,417 |
