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 56,550,445, 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 | 56,550,445 | |
| -1 | -56,550,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,550,445.
Example:
1 x 56,550,445 = 56,550,445
and
-1 x -56,550,445 = 56,550,445
Notice both answers equal 56,550,445
With that explanation out of the way, let's continue. Next, we take the number 56,550,445 and divide it by 2:
56,550,445 ÷ 2 = 28,275,222.5
If the quotient is a whole number, then 2 and 28,275,222.5 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 | 56,550,445 | |
| -1 | -56,550,445 |
Now, we try dividing 56,550,445 by 3:
56,550,445 ÷ 3 = 18,850,148.3333
If the quotient is a whole number, then 3 and 18,850,148.3333 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 | 56,550,445 | |
| -1 | -56,550,445 |
Let's try dividing by 4:
56,550,445 ÷ 4 = 14,137,611.25
If the quotient is a whole number, then 4 and 14,137,611.25 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 | 56,550,445 | |
| -1 | 56,550,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 70,249 | 351,245 | 491,743 | 1,615,727 | 2,458,715 | 8,078,635 | 11,310,089 | 56,550,445 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -70,249 | -351,245 | -491,743 | -1,615,727 | -2,458,715 | -8,078,635 | -11,310,089 | -56,550,445 |
