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 77,734,019, 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 | 77,734,019 | |
| -1 | -77,734,019 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 77,734,019.
Example:
1 x 77,734,019 = 77,734,019
and
-1 x -77,734,019 = 77,734,019
Notice both answers equal 77,734,019
With that explanation out of the way, let's continue. Next, we take the number 77,734,019 and divide it by 2:
77,734,019 ÷ 2 = 38,867,009.5
If the quotient is a whole number, then 2 and 38,867,009.5 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 | 77,734,019 | |
| -1 | -77,734,019 |
Now, we try dividing 77,734,019 by 3:
77,734,019 ÷ 3 = 25,911,339.6667
If the quotient is a whole number, then 3 and 25,911,339.6667 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 | 77,734,019 | |
| -1 | -77,734,019 |
Let's try dividing by 4:
77,734,019 ÷ 4 = 19,433,504.75
If the quotient is a whole number, then 4 and 19,433,504.75 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 | 77,734,019 | |
| -1 | 77,734,019 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 257 | 341 | 887 | 2,827 | 7,967 | 9,757 | 27,497 | 87,637 | 227,959 | 302,467 | 2,507,549 | 7,066,729 | 77,734,019 |
| -1 | -11 | -31 | -257 | -341 | -887 | -2,827 | -7,967 | -9,757 | -27,497 | -87,637 | -227,959 | -302,467 | -2,507,549 | -7,066,729 | -77,734,019 |
