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 54,505,123, 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 | 54,505,123 | |
| -1 | -54,505,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,505,123.
Example:
1 x 54,505,123 = 54,505,123
and
-1 x -54,505,123 = 54,505,123
Notice both answers equal 54,505,123
With that explanation out of the way, let's continue. Next, we take the number 54,505,123 and divide it by 2:
54,505,123 ÷ 2 = 27,252,561.5
If the quotient is a whole number, then 2 and 27,252,561.5 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 | 54,505,123 | |
| -1 | -54,505,123 |
Now, we try dividing 54,505,123 by 3:
54,505,123 ÷ 3 = 18,168,374.3333
If the quotient is a whole number, then 3 and 18,168,374.3333 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 | 54,505,123 | |
| -1 | -54,505,123 |
Let's try dividing by 4:
54,505,123 ÷ 4 = 13,626,280.75
If the quotient is a whole number, then 4 and 13,626,280.75 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 | 54,505,123 | |
| -1 | 54,505,123 |
If you did it right, you will end up with this table:
| 1 | 29 | 43 | 109 | 401 | 1,247 | 3,161 | 4,687 | 11,629 | 17,243 | 43,709 | 135,923 | 500,047 | 1,267,561 | 1,879,487 | 54,505,123 |
| -1 | -29 | -43 | -109 | -401 | -1,247 | -3,161 | -4,687 | -11,629 | -17,243 | -43,709 | -135,923 | -500,047 | -1,267,561 | -1,879,487 | -54,505,123 |
