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 77,556,061, 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 | 77,556,061 | |
| -1 | -77,556,061 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 77,556,061.
Example:
1 x 77,556,061 = 77,556,061
and
-1 x -77,556,061 = 77,556,061
Notice both answers equal 77,556,061
With that explanation out of the way, let's continue. Next, we take the number 77,556,061 and divide it by 2:
77,556,061 ÷ 2 = 38,778,030.5
If the quotient is a whole number, then 2 and 38,778,030.5 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 | 77,556,061 | |
| -1 | -77,556,061 |
Now, we try dividing 77,556,061 by 3:
77,556,061 ÷ 3 = 25,852,020.3333
If the quotient is a whole number, then 3 and 25,852,020.3333 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 | 77,556,061 | |
| -1 | -77,556,061 |
Let's try dividing by 4:
77,556,061 ÷ 4 = 19,389,015.25
If the quotient is a whole number, then 4 and 19,389,015.25 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 | 77,556,061 | |
| -1 | 77,556,061 |
If you did it right, you will end up with this table:
| 1 | 11 | 107 | 131 | 503 | 1,177 | 1,441 | 5,533 | 14,017 | 53,821 | 65,893 | 154,187 | 592,031 | 724,823 | 7,050,551 | 77,556,061 |
| -1 | -11 | -107 | -131 | -503 | -1,177 | -1,441 | -5,533 | -14,017 | -53,821 | -65,893 | -154,187 | -592,031 | -724,823 | -7,050,551 | -77,556,061 |
