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 77,346,775, 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 | 77,346,775 | |
| -1 | -77,346,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 77,346,775.
Example:
1 x 77,346,775 = 77,346,775
and
-1 x -77,346,775 = 77,346,775
Notice both answers equal 77,346,775
With that explanation out of the way, let's continue. Next, we take the number 77,346,775 and divide it by 2:
77,346,775 ÷ 2 = 38,673,387.5
If the quotient is a whole number, then 2 and 38,673,387.5 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 | 77,346,775 | |
| -1 | -77,346,775 |
Now, we try dividing 77,346,775 by 3:
77,346,775 ÷ 3 = 25,782,258.3333
If the quotient is a whole number, then 3 and 25,782,258.3333 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 | 77,346,775 | |
| -1 | -77,346,775 |
Let's try dividing by 4:
77,346,775 ÷ 4 = 19,336,693.75
If the quotient is a whole number, then 4 and 19,336,693.75 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 | 77,346,775 | |
| -1 | 77,346,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 137 | 275 | 685 | 1,507 | 2,053 | 3,425 | 7,535 | 10,265 | 22,583 | 37,675 | 51,325 | 112,915 | 281,261 | 564,575 | 1,406,305 | 3,093,871 | 7,031,525 | 15,469,355 | 77,346,775 |
| -1 | -5 | -11 | -25 | -55 | -137 | -275 | -685 | -1,507 | -2,053 | -3,425 | -7,535 | -10,265 | -22,583 | -37,675 | -51,325 | -112,915 | -281,261 | -564,575 | -1,406,305 | -3,093,871 | -7,031,525 | -15,469,355 | -77,346,775 |
