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 55,856,645, 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 | 55,856,645 | |
| -1 | -55,856,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,856,645.
Example:
1 x 55,856,645 = 55,856,645
and
-1 x -55,856,645 = 55,856,645
Notice both answers equal 55,856,645
With that explanation out of the way, let's continue. Next, we take the number 55,856,645 and divide it by 2:
55,856,645 ÷ 2 = 27,928,322.5
If the quotient is a whole number, then 2 and 27,928,322.5 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 | 55,856,645 | |
| -1 | -55,856,645 |
Now, we try dividing 55,856,645 by 3:
55,856,645 ÷ 3 = 18,618,881.6667
If the quotient is a whole number, then 3 and 18,618,881.6667 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 | 55,856,645 | |
| -1 | -55,856,645 |
Let's try dividing by 4:
55,856,645 ÷ 4 = 13,964,161.25
If the quotient is a whole number, then 4 and 13,964,161.25 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 | 55,856,645 | |
| -1 | 55,856,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 50,549 | 252,745 | 657,137 | 859,333 | 3,285,685 | 4,296,665 | 11,171,329 | 55,856,645 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -50,549 | -252,745 | -657,137 | -859,333 | -3,285,685 | -4,296,665 | -11,171,329 | -55,856,645 |
