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 56,207,723, 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 | 56,207,723 | |
| -1 | -56,207,723 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,207,723.
Example:
1 x 56,207,723 = 56,207,723
and
-1 x -56,207,723 = 56,207,723
Notice both answers equal 56,207,723
With that explanation out of the way, let's continue. Next, we take the number 56,207,723 and divide it by 2:
56,207,723 ÷ 2 = 28,103,861.5
If the quotient is a whole number, then 2 and 28,103,861.5 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 | 56,207,723 | |
| -1 | -56,207,723 |
Now, we try dividing 56,207,723 by 3:
56,207,723 ÷ 3 = 18,735,907.6667
If the quotient is a whole number, then 3 and 18,735,907.6667 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 | 56,207,723 | |
| -1 | -56,207,723 |
Let's try dividing by 4:
56,207,723 ÷ 4 = 14,051,930.75
If the quotient is a whole number, then 4 and 14,051,930.75 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 | 56,207,723 | |
| -1 | 56,207,723 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 47 | 143 | 517 | 611 | 6,721 | 8,363 | 91,993 | 108,719 | 393,061 | 1,195,909 | 4,323,671 | 5,109,793 | 56,207,723 |
| -1 | -11 | -13 | -47 | -143 | -517 | -611 | -6,721 | -8,363 | -91,993 | -108,719 | -393,061 | -1,195,909 | -4,323,671 | -5,109,793 | -56,207,723 |
