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 76,102,507, 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 | 76,102,507 | |
| -1 | -76,102,507 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,102,507.
Example:
1 x 76,102,507 = 76,102,507
and
-1 x -76,102,507 = 76,102,507
Notice both answers equal 76,102,507
With that explanation out of the way, let's continue. Next, we take the number 76,102,507 and divide it by 2:
76,102,507 ÷ 2 = 38,051,253.5
If the quotient is a whole number, then 2 and 38,051,253.5 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 | 76,102,507 | |
| -1 | -76,102,507 |
Now, we try dividing 76,102,507 by 3:
76,102,507 ÷ 3 = 25,367,502.3333
If the quotient is a whole number, then 3 and 25,367,502.3333 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 | 76,102,507 | |
| -1 | -76,102,507 |
Let's try dividing by 4:
76,102,507 ÷ 4 = 19,025,626.75
If the quotient is a whole number, then 4 and 19,025,626.75 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 | 76,102,507 | |
| -1 | 76,102,507 |
If you did it right, you will end up with this table:
| 1 | 13 | 59 | 313 | 317 | 767 | 4,069 | 4,121 | 18,467 | 18,703 | 99,221 | 240,071 | 243,139 | 1,289,873 | 5,854,039 | 76,102,507 |
| -1 | -13 | -59 | -313 | -317 | -767 | -4,069 | -4,121 | -18,467 | -18,703 | -99,221 | -240,071 | -243,139 | -1,289,873 | -5,854,039 | -76,102,507 |
