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 69,793,009, 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 | 69,793,009 | |
| -1 | -69,793,009 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,793,009.
Example:
1 x 69,793,009 = 69,793,009
and
-1 x -69,793,009 = 69,793,009
Notice both answers equal 69,793,009
With that explanation out of the way, let's continue. Next, we take the number 69,793,009 and divide it by 2:
69,793,009 ÷ 2 = 34,896,504.5
If the quotient is a whole number, then 2 and 34,896,504.5 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 | 69,793,009 | |
| -1 | -69,793,009 |
Now, we try dividing 69,793,009 by 3:
69,793,009 ÷ 3 = 23,264,336.3333
If the quotient is a whole number, then 3 and 23,264,336.3333 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 | 69,793,009 | |
| -1 | -69,793,009 |
Let's try dividing by 4:
69,793,009 ÷ 4 = 17,448,252.25
If the quotient is a whole number, then 4 and 17,448,252.25 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 | 69,793,009 | |
| -1 | 69,793,009 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 449 | 1,087 | 4,939 | 5,837 | 11,957 | 14,131 | 64,207 | 155,441 | 488,063 | 5,368,693 | 6,344,819 | 69,793,009 |
| -1 | -11 | -13 | -143 | -449 | -1,087 | -4,939 | -5,837 | -11,957 | -14,131 | -64,207 | -155,441 | -488,063 | -5,368,693 | -6,344,819 | -69,793,009 |
