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 13,269,395, 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 | 13,269,395 | |
| -1 | -13,269,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,269,395.
Example:
1 x 13,269,395 = 13,269,395
and
-1 x -13,269,395 = 13,269,395
Notice both answers equal 13,269,395
With that explanation out of the way, let's continue. Next, we take the number 13,269,395 and divide it by 2:
13,269,395 ÷ 2 = 6,634,697.5
If the quotient is a whole number, then 2 and 6,634,697.5 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 | 13,269,395 | |
| -1 | -13,269,395 |
Now, we try dividing 13,269,395 by 3:
13,269,395 ÷ 3 = 4,423,131.6667
If the quotient is a whole number, then 3 and 4,423,131.6667 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 | 13,269,395 | |
| -1 | -13,269,395 |
Let's try dividing by 4:
13,269,395 ÷ 4 = 3,317,348.75
If the quotient is a whole number, then 4 and 3,317,348.75 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 | 13,269,395 | |
| -1 | 13,269,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 59 | 155 | 295 | 1,451 | 1,829 | 7,255 | 9,145 | 44,981 | 85,609 | 224,905 | 428,045 | 2,653,879 | 13,269,395 |
| -1 | -5 | -31 | -59 | -155 | -295 | -1,451 | -1,829 | -7,255 | -9,145 | -44,981 | -85,609 | -224,905 | -428,045 | -2,653,879 | -13,269,395 |
