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 31,336,637, 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 | 31,336,637 | |
| -1 | -31,336,637 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,336,637.
Example:
1 x 31,336,637 = 31,336,637
and
-1 x -31,336,637 = 31,336,637
Notice both answers equal 31,336,637
With that explanation out of the way, let's continue. Next, we take the number 31,336,637 and divide it by 2:
31,336,637 ÷ 2 = 15,668,318.5
If the quotient is a whole number, then 2 and 15,668,318.5 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 | 31,336,637 | |
| -1 | -31,336,637 |
Now, we try dividing 31,336,637 by 3:
31,336,637 ÷ 3 = 10,445,545.6667
If the quotient is a whole number, then 3 and 10,445,545.6667 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 | 31,336,637 | |
| -1 | -31,336,637 |
Let's try dividing by 4:
31,336,637 ÷ 4 = 7,834,159.25
If the quotient is a whole number, then 4 and 7,834,159.25 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 | 31,336,637 | |
| -1 | 31,336,637 |
If you did it right, you will end up with this table:
| 1 | 43 | 67 | 73 | 149 | 2,881 | 3,139 | 4,891 | 6,407 | 9,983 | 10,877 | 210,313 | 429,269 | 467,711 | 728,759 | 31,336,637 |
| -1 | -43 | -67 | -73 | -149 | -2,881 | -3,139 | -4,891 | -6,407 | -9,983 | -10,877 | -210,313 | -429,269 | -467,711 | -728,759 | -31,336,637 |
