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 77,717,675, 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 | 77,717,675 | |
| -1 | -77,717,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 77,717,675.
Example:
1 x 77,717,675 = 77,717,675
and
-1 x -77,717,675 = 77,717,675
Notice both answers equal 77,717,675
With that explanation out of the way, let's continue. Next, we take the number 77,717,675 and divide it by 2:
77,717,675 ÷ 2 = 38,858,837.5
If the quotient is a whole number, then 2 and 38,858,837.5 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 | 77,717,675 | |
| -1 | -77,717,675 |
Now, we try dividing 77,717,675 by 3:
77,717,675 ÷ 3 = 25,905,891.6667
If the quotient is a whole number, then 3 and 25,905,891.6667 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 | 77,717,675 | |
| -1 | -77,717,675 |
Let's try dividing by 4:
77,717,675 ÷ 4 = 19,429,418.75
If the quotient is a whole number, then 4 and 19,429,418.75 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 | 77,717,675 | |
| -1 | 77,717,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 63,443 | 317,215 | 444,101 | 1,586,075 | 2,220,505 | 3,108,707 | 11,102,525 | 15,543,535 | 77,717,675 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -63,443 | -317,215 | -444,101 | -1,586,075 | -2,220,505 | -3,108,707 | -11,102,525 | -15,543,535 | -77,717,675 |
