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 56,021,477, 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 | 56,021,477 | |
| -1 | -56,021,477 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,021,477.
Example:
1 x 56,021,477 = 56,021,477
and
-1 x -56,021,477 = 56,021,477
Notice both answers equal 56,021,477
With that explanation out of the way, let's continue. Next, we take the number 56,021,477 and divide it by 2:
56,021,477 ÷ 2 = 28,010,738.5
If the quotient is a whole number, then 2 and 28,010,738.5 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 | 56,021,477 | |
| -1 | -56,021,477 |
Now, we try dividing 56,021,477 by 3:
56,021,477 ÷ 3 = 18,673,825.6667
If the quotient is a whole number, then 3 and 18,673,825.6667 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 | 56,021,477 | |
| -1 | -56,021,477 |
Let's try dividing by 4:
56,021,477 ÷ 4 = 14,005,369.25
If the quotient is a whole number, then 4 and 14,005,369.25 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 | 56,021,477 | |
| -1 | 56,021,477 |
If you did it right, you will end up with this table:
| 1 | 17 | 53 | 97 | 641 | 901 | 1,649 | 5,141 | 10,897 | 33,973 | 62,177 | 87,397 | 577,541 | 1,057,009 | 3,295,381 | 56,021,477 |
| -1 | -17 | -53 | -97 | -641 | -901 | -1,649 | -5,141 | -10,897 | -33,973 | -62,177 | -87,397 | -577,541 | -1,057,009 | -3,295,381 | -56,021,477 |
