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 76,090,777, 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 | 76,090,777 | |
| -1 | -76,090,777 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,090,777.
Example:
1 x 76,090,777 = 76,090,777
and
-1 x -76,090,777 = 76,090,777
Notice both answers equal 76,090,777
With that explanation out of the way, let's continue. Next, we take the number 76,090,777 and divide it by 2:
76,090,777 ÷ 2 = 38,045,388.5
If the quotient is a whole number, then 2 and 38,045,388.5 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 | 76,090,777 | |
| -1 | -76,090,777 |
Now, we try dividing 76,090,777 by 3:
76,090,777 ÷ 3 = 25,363,592.3333
If the quotient is a whole number, then 3 and 25,363,592.3333 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 | 76,090,777 | |
| -1 | -76,090,777 |
Let's try dividing by 4:
76,090,777 ÷ 4 = 19,022,694.25
If the quotient is a whole number, then 4 and 19,022,694.25 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 | 76,090,777 | |
| -1 | 76,090,777 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 97 | 343 | 679 | 2,287 | 4,753 | 16,009 | 33,271 | 112,063 | 221,839 | 784,441 | 1,552,873 | 10,870,111 | 76,090,777 |
| -1 | -7 | -49 | -97 | -343 | -679 | -2,287 | -4,753 | -16,009 | -33,271 | -112,063 | -221,839 | -784,441 | -1,552,873 | -10,870,111 | -76,090,777 |
