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 69,192,109, 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 | 69,192,109 | |
| -1 | -69,192,109 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,192,109.
Example:
1 x 69,192,109 = 69,192,109
and
-1 x -69,192,109 = 69,192,109
Notice both answers equal 69,192,109
With that explanation out of the way, let's continue. Next, we take the number 69,192,109 and divide it by 2:
69,192,109 ÷ 2 = 34,596,054.5
If the quotient is a whole number, then 2 and 34,596,054.5 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 | 69,192,109 | |
| -1 | -69,192,109 |
Now, we try dividing 69,192,109 by 3:
69,192,109 ÷ 3 = 23,064,036.3333
If the quotient is a whole number, then 3 and 23,064,036.3333 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 | 69,192,109 | |
| -1 | -69,192,109 |
Let's try dividing by 4:
69,192,109 ÷ 4 = 17,298,027.25
If the quotient is a whole number, then 4 and 17,298,027.25 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 | 69,192,109 | |
| -1 | 69,192,109 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 259 | 463 | 577 | 3,241 | 4,039 | 17,131 | 21,349 | 119,917 | 149,443 | 267,151 | 1,870,057 | 9,884,587 | 69,192,109 |
| -1 | -7 | -37 | -259 | -463 | -577 | -3,241 | -4,039 | -17,131 | -21,349 | -119,917 | -149,443 | -267,151 | -1,870,057 | -9,884,587 | -69,192,109 |
