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 67,630,031, 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 | 67,630,031 | |
| -1 | -67,630,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,630,031.
Example:
1 x 67,630,031 = 67,630,031
and
-1 x -67,630,031 = 67,630,031
Notice both answers equal 67,630,031
With that explanation out of the way, let's continue. Next, we take the number 67,630,031 and divide it by 2:
67,630,031 ÷ 2 = 33,815,015.5
If the quotient is a whole number, then 2 and 33,815,015.5 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 | 67,630,031 | |
| -1 | -67,630,031 |
Now, we try dividing 67,630,031 by 3:
67,630,031 ÷ 3 = 22,543,343.6667
If the quotient is a whole number, then 3 and 22,543,343.6667 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 | 67,630,031 | |
| -1 | -67,630,031 |
Let's try dividing by 4:
67,630,031 ÷ 4 = 16,907,507.75
If the quotient is a whole number, then 4 and 16,907,507.75 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 | 67,630,031 | |
| -1 | 67,630,031 |
If you did it right, you will end up with this table:
| 1 | 7 | 109 | 151 | 587 | 763 | 1,057 | 4,109 | 16,459 | 63,983 | 88,637 | 115,213 | 447,881 | 620,459 | 9,661,433 | 67,630,031 |
| -1 | -7 | -109 | -151 | -587 | -763 | -1,057 | -4,109 | -16,459 | -63,983 | -88,637 | -115,213 | -447,881 | -620,459 | -9,661,433 | -67,630,031 |
