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 55,432,505, 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 | 55,432,505 | |
| -1 | -55,432,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,432,505.
Example:
1 x 55,432,505 = 55,432,505
and
-1 x -55,432,505 = 55,432,505
Notice both answers equal 55,432,505
With that explanation out of the way, let's continue. Next, we take the number 55,432,505 and divide it by 2:
55,432,505 ÷ 2 = 27,716,252.5
If the quotient is a whole number, then 2 and 27,716,252.5 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 | 55,432,505 | |
| -1 | -55,432,505 |
Now, we try dividing 55,432,505 by 3:
55,432,505 ÷ 3 = 18,477,501.6667
If the quotient is a whole number, then 3 and 18,477,501.6667 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 | 55,432,505 | |
| -1 | -55,432,505 |
Let's try dividing by 4:
55,432,505 ÷ 4 = 13,858,126.25
If the quotient is a whole number, then 4 and 13,858,126.25 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 | 55,432,505 | |
| -1 | 55,432,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 139 | 235 | 695 | 1,697 | 6,533 | 8,485 | 32,665 | 79,759 | 235,883 | 398,795 | 1,179,415 | 11,086,501 | 55,432,505 |
| -1 | -5 | -47 | -139 | -235 | -695 | -1,697 | -6,533 | -8,485 | -32,665 | -79,759 | -235,883 | -398,795 | -1,179,415 | -11,086,501 | -55,432,505 |
