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 55,856,647, 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 | 55,856,647 | |
| -1 | -55,856,647 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,856,647.
Example:
1 x 55,856,647 = 55,856,647
and
-1 x -55,856,647 = 55,856,647
Notice both answers equal 55,856,647
With that explanation out of the way, let's continue. Next, we take the number 55,856,647 and divide it by 2:
55,856,647 ÷ 2 = 27,928,323.5
If the quotient is a whole number, then 2 and 27,928,323.5 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 | 55,856,647 | |
| -1 | -55,856,647 |
Now, we try dividing 55,856,647 by 3:
55,856,647 ÷ 3 = 18,618,882.3333
If the quotient is a whole number, then 3 and 18,618,882.3333 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 | 55,856,647 | |
| -1 | -55,856,647 |
Let's try dividing by 4:
55,856,647 ÷ 4 = 13,964,161.75
If the quotient is a whole number, then 4 and 13,964,161.75 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 | 55,856,647 | |
| -1 | 55,856,647 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 53 | 77 | 371 | 583 | 4,081 | 13,687 | 95,809 | 150,557 | 725,411 | 1,053,899 | 5,077,877 | 7,979,521 | 55,856,647 |
| -1 | -7 | -11 | -53 | -77 | -371 | -583 | -4,081 | -13,687 | -95,809 | -150,557 | -725,411 | -1,053,899 | -5,077,877 | -7,979,521 | -55,856,647 |
