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 69,269,135, 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 | 69,269,135 | |
| -1 | -69,269,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 69,269,135.
Example:
1 x 69,269,135 = 69,269,135
and
-1 x -69,269,135 = 69,269,135
Notice both answers equal 69,269,135
With that explanation out of the way, let's continue. Next, we take the number 69,269,135 and divide it by 2:
69,269,135 ÷ 2 = 34,634,567.5
If the quotient is a whole number, then 2 and 34,634,567.5 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 | 69,269,135 | |
| -1 | -69,269,135 |
Now, we try dividing 69,269,135 by 3:
69,269,135 ÷ 3 = 23,089,711.6667
If the quotient is a whole number, then 3 and 23,089,711.6667 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 | 69,269,135 | |
| -1 | -69,269,135 |
Let's try dividing by 4:
69,269,135 ÷ 4 = 17,317,283.75
If the quotient is a whole number, then 4 and 17,317,283.75 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 | 69,269,135 | |
| -1 | 69,269,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 62,687 | 313,435 | 814,931 | 1,065,679 | 4,074,655 | 5,328,395 | 13,853,827 | 69,269,135 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -62,687 | -313,435 | -814,931 | -1,065,679 | -4,074,655 | -5,328,395 | -13,853,827 | -69,269,135 |
