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 31,701,425, 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 | 31,701,425 | |
| -1 | -31,701,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,701,425.
Example:
1 x 31,701,425 = 31,701,425
and
-1 x -31,701,425 = 31,701,425
Notice both answers equal 31,701,425
With that explanation out of the way, let's continue. Next, we take the number 31,701,425 and divide it by 2:
31,701,425 ÷ 2 = 15,850,712.5
If the quotient is a whole number, then 2 and 15,850,712.5 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 | 31,701,425 | |
| -1 | -31,701,425 |
Now, we try dividing 31,701,425 by 3:
31,701,425 ÷ 3 = 10,567,141.6667
If the quotient is a whole number, then 3 and 10,567,141.6667 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 | 31,701,425 | |
| -1 | -31,701,425 |
Let's try dividing by 4:
31,701,425 ÷ 4 = 7,925,356.25
If the quotient is a whole number, then 4 and 7,925,356.25 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 | 31,701,425 | |
| -1 | 31,701,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 107 | 175 | 535 | 749 | 1,693 | 2,675 | 3,745 | 8,465 | 11,851 | 18,725 | 42,325 | 59,255 | 181,151 | 296,275 | 905,755 | 1,268,057 | 4,528,775 | 6,340,285 | 31,701,425 |
| -1 | -5 | -7 | -25 | -35 | -107 | -175 | -535 | -749 | -1,693 | -2,675 | -3,745 | -8,465 | -11,851 | -18,725 | -42,325 | -59,255 | -181,151 | -296,275 | -905,755 | -1,268,057 | -4,528,775 | -6,340,285 | -31,701,425 |
