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 76,006,625, 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 | 76,006,625 | |
| -1 | -76,006,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,006,625.
Example:
1 x 76,006,625 = 76,006,625
and
-1 x -76,006,625 = 76,006,625
Notice both answers equal 76,006,625
With that explanation out of the way, let's continue. Next, we take the number 76,006,625 and divide it by 2:
76,006,625 ÷ 2 = 38,003,312.5
If the quotient is a whole number, then 2 and 38,003,312.5 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 | 76,006,625 | |
| -1 | -76,006,625 |
Now, we try dividing 76,006,625 by 3:
76,006,625 ÷ 3 = 25,335,541.6667
If the quotient is a whole number, then 3 and 25,335,541.6667 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 | 76,006,625 | |
| -1 | -76,006,625 |
Let's try dividing by 4:
76,006,625 ÷ 4 = 19,001,656.25
If the quotient is a whole number, then 4 and 19,001,656.25 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 | 76,006,625 | |
| -1 | 76,006,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 113 | 125 | 565 | 2,825 | 5,381 | 14,125 | 26,905 | 134,525 | 608,053 | 672,625 | 3,040,265 | 15,201,325 | 76,006,625 |
| -1 | -5 | -25 | -113 | -125 | -565 | -2,825 | -5,381 | -14,125 | -26,905 | -134,525 | -608,053 | -672,625 | -3,040,265 | -15,201,325 | -76,006,625 |
