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 55,907,951, 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 | 55,907,951 | |
| -1 | -55,907,951 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,907,951.
Example:
1 x 55,907,951 = 55,907,951
and
-1 x -55,907,951 = 55,907,951
Notice both answers equal 55,907,951
With that explanation out of the way, let's continue. Next, we take the number 55,907,951 and divide it by 2:
55,907,951 ÷ 2 = 27,953,975.5
If the quotient is a whole number, then 2 and 27,953,975.5 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 | 55,907,951 | |
| -1 | -55,907,951 |
Now, we try dividing 55,907,951 by 3:
55,907,951 ÷ 3 = 18,635,983.6667
If the quotient is a whole number, then 3 and 18,635,983.6667 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 | 55,907,951 | |
| -1 | -55,907,951 |
Let's try dividing by 4:
55,907,951 ÷ 4 = 13,976,987.75
If the quotient is a whole number, then 4 and 13,976,987.75 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 | 55,907,951 | |
| -1 | 55,907,951 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 53 | 187 | 583 | 901 | 5,641 | 9,911 | 62,051 | 95,897 | 298,973 | 1,054,867 | 3,288,703 | 5,082,541 | 55,907,951 |
| -1 | -11 | -17 | -53 | -187 | -583 | -901 | -5,641 | -9,911 | -62,051 | -95,897 | -298,973 | -1,054,867 | -3,288,703 | -5,082,541 | -55,907,951 |
