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 67,032,007, 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 | 67,032,007 | |
| -1 | -67,032,007 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,032,007.
Example:
1 x 67,032,007 = 67,032,007
and
-1 x -67,032,007 = 67,032,007
Notice both answers equal 67,032,007
With that explanation out of the way, let's continue. Next, we take the number 67,032,007 and divide it by 2:
67,032,007 ÷ 2 = 33,516,003.5
If the quotient is a whole number, then 2 and 33,516,003.5 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 | 67,032,007 | |
| -1 | -67,032,007 |
Now, we try dividing 67,032,007 by 3:
67,032,007 ÷ 3 = 22,344,002.3333
If the quotient is a whole number, then 3 and 22,344,002.3333 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 | 67,032,007 | |
| -1 | -67,032,007 |
Let's try dividing by 4:
67,032,007 ÷ 4 = 16,758,001.75
If the quotient is a whole number, then 4 and 16,758,001.75 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 | 67,032,007 | |
| -1 | 67,032,007 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 287 | 311 | 751 | 2,177 | 5,257 | 12,751 | 30,791 | 89,257 | 215,537 | 233,561 | 1,634,927 | 9,576,001 | 67,032,007 |
| -1 | -7 | -41 | -287 | -311 | -751 | -2,177 | -5,257 | -12,751 | -30,791 | -89,257 | -215,537 | -233,561 | -1,634,927 | -9,576,001 | -67,032,007 |
