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 54,519,395, 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 | 54,519,395 | |
| -1 | -54,519,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,519,395.
Example:
1 x 54,519,395 = 54,519,395
and
-1 x -54,519,395 = 54,519,395
Notice both answers equal 54,519,395
With that explanation out of the way, let's continue. Next, we take the number 54,519,395 and divide it by 2:
54,519,395 ÷ 2 = 27,259,697.5
If the quotient is a whole number, then 2 and 27,259,697.5 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 | 54,519,395 | |
| -1 | -54,519,395 |
Now, we try dividing 54,519,395 by 3:
54,519,395 ÷ 3 = 18,173,131.6667
If the quotient is a whole number, then 3 and 18,173,131.6667 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 | 54,519,395 | |
| -1 | -54,519,395 |
Let's try dividing by 4:
54,519,395 ÷ 4 = 13,629,848.75
If the quotient is a whole number, then 4 and 13,629,848.75 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 | 54,519,395 | |
| -1 | 54,519,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,201 | 1,297 | 6,005 | 6,485 | 8,407 | 9,079 | 42,035 | 45,395 | 1,557,697 | 7,788,485 | 10,903,879 | 54,519,395 |
| -1 | -5 | -7 | -35 | -1,201 | -1,297 | -6,005 | -6,485 | -8,407 | -9,079 | -42,035 | -45,395 | -1,557,697 | -7,788,485 | -10,903,879 | -54,519,395 |
