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 69,557,605, 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 | 69,557,605 | |
| -1 | -69,557,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,557,605.
Example:
1 x 69,557,605 = 69,557,605
and
-1 x -69,557,605 = 69,557,605
Notice both answers equal 69,557,605
With that explanation out of the way, let's continue. Next, we take the number 69,557,605 and divide it by 2:
69,557,605 ÷ 2 = 34,778,802.5
If the quotient is a whole number, then 2 and 34,778,802.5 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 | 69,557,605 | |
| -1 | -69,557,605 |
Now, we try dividing 69,557,605 by 3:
69,557,605 ÷ 3 = 23,185,868.3333
If the quotient is a whole number, then 3 and 23,185,868.3333 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 | 69,557,605 | |
| -1 | -69,557,605 |
Let's try dividing by 4:
69,557,605 ÷ 4 = 17,389,401.25
If the quotient is a whole number, then 4 and 17,389,401.25 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 | 69,557,605 | |
| -1 | 69,557,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 229 | 1,145 | 2,977 | 4,673 | 14,885 | 23,365 | 60,749 | 303,745 | 1,070,117 | 5,350,585 | 13,911,521 | 69,557,605 |
| -1 | -5 | -13 | -65 | -229 | -1,145 | -2,977 | -4,673 | -14,885 | -23,365 | -60,749 | -303,745 | -1,070,117 | -5,350,585 | -13,911,521 | -69,557,605 |
