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 76,287,659, 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 | 76,287,659 | |
| -1 | -76,287,659 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,287,659.
Example:
1 x 76,287,659 = 76,287,659
and
-1 x -76,287,659 = 76,287,659
Notice both answers equal 76,287,659
With that explanation out of the way, let's continue. Next, we take the number 76,287,659 and divide it by 2:
76,287,659 ÷ 2 = 38,143,829.5
If the quotient is a whole number, then 2 and 38,143,829.5 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 | 76,287,659 | |
| -1 | -76,287,659 |
Now, we try dividing 76,287,659 by 3:
76,287,659 ÷ 3 = 25,429,219.6667
If the quotient is a whole number, then 3 and 25,429,219.6667 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 | 76,287,659 | |
| -1 | -76,287,659 |
Let's try dividing by 4:
76,287,659 ÷ 4 = 19,071,914.75
If the quotient is a whole number, then 4 and 19,071,914.75 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 | 76,287,659 | |
| -1 | 76,287,659 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 197 | 343 | 1,129 | 1,379 | 7,903 | 9,653 | 55,321 | 67,571 | 222,413 | 387,247 | 1,556,891 | 10,898,237 | 76,287,659 |
| -1 | -7 | -49 | -197 | -343 | -1,129 | -1,379 | -7,903 | -9,653 | -55,321 | -67,571 | -222,413 | -387,247 | -1,556,891 | -10,898,237 | -76,287,659 |
