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 56,552,405, 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 | 56,552,405 | |
| -1 | -56,552,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,552,405.
Example:
1 x 56,552,405 = 56,552,405
and
-1 x -56,552,405 = 56,552,405
Notice both answers equal 56,552,405
With that explanation out of the way, let's continue. Next, we take the number 56,552,405 and divide it by 2:
56,552,405 ÷ 2 = 28,276,202.5
If the quotient is a whole number, then 2 and 28,276,202.5 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 | 56,552,405 | |
| -1 | -56,552,405 |
Now, we try dividing 56,552,405 by 3:
56,552,405 ÷ 3 = 18,850,801.6667
If the quotient is a whole number, then 3 and 18,850,801.6667 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 | 56,552,405 | |
| -1 | -56,552,405 |
Let's try dividing by 4:
56,552,405 ÷ 4 = 14,138,101.25
If the quotient is a whole number, then 4 and 14,138,101.25 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 | 56,552,405 | |
| -1 | 56,552,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 124,291 | 621,455 | 870,037 | 1,615,783 | 4,350,185 | 8,078,915 | 11,310,481 | 56,552,405 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -124,291 | -621,455 | -870,037 | -1,615,783 | -4,350,185 | -8,078,915 | -11,310,481 | -56,552,405 |
