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 56,131,669, 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 | 56,131,669 | |
| -1 | -56,131,669 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,131,669.
Example:
1 x 56,131,669 = 56,131,669
and
-1 x -56,131,669 = 56,131,669
Notice both answers equal 56,131,669
With that explanation out of the way, let's continue. Next, we take the number 56,131,669 and divide it by 2:
56,131,669 ÷ 2 = 28,065,834.5
If the quotient is a whole number, then 2 and 28,065,834.5 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 | 56,131,669 | |
| -1 | -56,131,669 |
Now, we try dividing 56,131,669 by 3:
56,131,669 ÷ 3 = 18,710,556.3333
If the quotient is a whole number, then 3 and 18,710,556.3333 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 | 56,131,669 | |
| -1 | -56,131,669 |
Let's try dividing by 4:
56,131,669 ÷ 4 = 14,032,917.25
If the quotient is a whole number, then 4 and 14,032,917.25 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 | 56,131,669 | |
| -1 | 56,131,669 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 97 | 341 | 1,067 | 1,697 | 3,007 | 18,667 | 33,077 | 52,607 | 164,609 | 578,677 | 1,810,699 | 5,102,879 | 56,131,669 |
| -1 | -11 | -31 | -97 | -341 | -1,067 | -1,697 | -3,007 | -18,667 | -33,077 | -52,607 | -164,609 | -578,677 | -1,810,699 | -5,102,879 | -56,131,669 |
