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 67,383,169, 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 | 67,383,169 | |
| -1 | -67,383,169 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,383,169.
Example:
1 x 67,383,169 = 67,383,169
and
-1 x -67,383,169 = 67,383,169
Notice both answers equal 67,383,169
With that explanation out of the way, let's continue. Next, we take the number 67,383,169 and divide it by 2:
67,383,169 ÷ 2 = 33,691,584.5
If the quotient is a whole number, then 2 and 33,691,584.5 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 | 67,383,169 | |
| -1 | -67,383,169 |
Now, we try dividing 67,383,169 by 3:
67,383,169 ÷ 3 = 22,461,056.3333
If the quotient is a whole number, then 3 and 22,461,056.3333 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 | 67,383,169 | |
| -1 | -67,383,169 |
Let's try dividing by 4:
67,383,169 ÷ 4 = 16,845,792.25
If the quotient is a whole number, then 4 and 16,845,792.25 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 | 67,383,169 | |
| -1 | 67,383,169 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 139 | 161 | 973 | 3,011 | 3,197 | 21,077 | 22,379 | 69,253 | 418,529 | 484,771 | 2,929,703 | 9,626,167 | 67,383,169 |
| -1 | -7 | -23 | -139 | -161 | -973 | -3,011 | -3,197 | -21,077 | -22,379 | -69,253 | -418,529 | -484,771 | -2,929,703 | -9,626,167 | -67,383,169 |
