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 67,623,479, 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 | 67,623,479 | |
| -1 | -67,623,479 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,623,479.
Example:
1 x 67,623,479 = 67,623,479
and
-1 x -67,623,479 = 67,623,479
Notice both answers equal 67,623,479
With that explanation out of the way, let's continue. Next, we take the number 67,623,479 and divide it by 2:
67,623,479 ÷ 2 = 33,811,739.5
If the quotient is a whole number, then 2 and 33,811,739.5 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 | 67,623,479 | |
| -1 | -67,623,479 |
Now, we try dividing 67,623,479 by 3:
67,623,479 ÷ 3 = 22,541,159.6667
If the quotient is a whole number, then 3 and 22,541,159.6667 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 | 67,623,479 | |
| -1 | -67,623,479 |
Let's try dividing by 4:
67,623,479 ÷ 4 = 16,905,869.75
If the quotient is a whole number, then 4 and 16,905,869.75 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 | 67,623,479 | |
| -1 | 67,623,479 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 343 | 539 | 3,773 | 17,923 | 125,461 | 197,153 | 878,227 | 1,380,071 | 6,147,589 | 9,660,497 | 67,623,479 |
| -1 | -7 | -11 | -49 | -77 | -343 | -539 | -3,773 | -17,923 | -125,461 | -197,153 | -878,227 | -1,380,071 | -6,147,589 | -9,660,497 | -67,623,479 |
