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 55,551,923, 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 | 55,551,923 | |
| -1 | -55,551,923 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,551,923.
Example:
1 x 55,551,923 = 55,551,923
and
-1 x -55,551,923 = 55,551,923
Notice both answers equal 55,551,923
With that explanation out of the way, let's continue. Next, we take the number 55,551,923 and divide it by 2:
55,551,923 ÷ 2 = 27,775,961.5
If the quotient is a whole number, then 2 and 27,775,961.5 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 | 55,551,923 | |
| -1 | -55,551,923 |
Now, we try dividing 55,551,923 by 3:
55,551,923 ÷ 3 = 18,517,307.6667
If the quotient is a whole number, then 3 and 18,517,307.6667 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 | 55,551,923 | |
| -1 | -55,551,923 |
Let's try dividing by 4:
55,551,923 ÷ 4 = 13,887,980.75
If the quotient is a whole number, then 4 and 13,887,980.75 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 | 55,551,923 | |
| -1 | 55,551,923 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 389 | 887 | 2,723 | 6,209 | 8,947 | 20,401 | 62,629 | 142,807 | 345,043 | 2,415,301 | 7,935,989 | 55,551,923 |
| -1 | -7 | -23 | -161 | -389 | -887 | -2,723 | -6,209 | -8,947 | -20,401 | -62,629 | -142,807 | -345,043 | -2,415,301 | -7,935,989 | -55,551,923 |
