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 77,753,611, 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 | 77,753,611 | |
| -1 | -77,753,611 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 77,753,611.
Example:
1 x 77,753,611 = 77,753,611
and
-1 x -77,753,611 = 77,753,611
Notice both answers equal 77,753,611
With that explanation out of the way, let's continue. Next, we take the number 77,753,611 and divide it by 2:
77,753,611 ÷ 2 = 38,876,805.5
If the quotient is a whole number, then 2 and 38,876,805.5 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 | 77,753,611 | |
| -1 | -77,753,611 |
Now, we try dividing 77,753,611 by 3:
77,753,611 ÷ 3 = 25,917,870.3333
If the quotient is a whole number, then 3 and 25,917,870.3333 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 | 77,753,611 | |
| -1 | -77,753,611 |
Let's try dividing by 4:
77,753,611 ÷ 4 = 19,438,402.75
If the quotient is a whole number, then 4 and 19,438,402.75 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 | 77,753,611 | |
| -1 | 77,753,611 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 31 | 377 | 403 | 899 | 6,653 | 11,687 | 86,489 | 192,937 | 206,243 | 2,508,181 | 2,681,159 | 5,981,047 | 77,753,611 |
| -1 | -13 | -29 | -31 | -377 | -403 | -899 | -6,653 | -11,687 | -86,489 | -192,937 | -206,243 | -2,508,181 | -2,681,159 | -5,981,047 | -77,753,611 |
