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 55,556,039, 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 | 55,556,039 | |
| -1 | -55,556,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,556,039.
Example:
1 x 55,556,039 = 55,556,039
and
-1 x -55,556,039 = 55,556,039
Notice both answers equal 55,556,039
With that explanation out of the way, let's continue. Next, we take the number 55,556,039 and divide it by 2:
55,556,039 ÷ 2 = 27,778,019.5
If the quotient is a whole number, then 2 and 27,778,019.5 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 | 55,556,039 | |
| -1 | -55,556,039 |
Now, we try dividing 55,556,039 by 3:
55,556,039 ÷ 3 = 18,518,679.6667
If the quotient is a whole number, then 3 and 18,518,679.6667 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 | 55,556,039 | |
| -1 | -55,556,039 |
Let's try dividing by 4:
55,556,039 ÷ 4 = 13,889,009.75
If the quotient is a whole number, then 4 and 13,889,009.75 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 | 55,556,039 | |
| -1 | 55,556,039 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 79 | 553 | 869 | 6,083 | 9,133 | 63,931 | 100,463 | 703,241 | 721,507 | 5,050,549 | 7,936,577 | 55,556,039 |
| -1 | -7 | -11 | -77 | -79 | -553 | -869 | -6,083 | -9,133 | -63,931 | -100,463 | -703,241 | -721,507 | -5,050,549 | -7,936,577 | -55,556,039 |
