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 31,064,555, 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 | 31,064,555 | |
| -1 | -31,064,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,064,555.
Example:
1 x 31,064,555 = 31,064,555
and
-1 x -31,064,555 = 31,064,555
Notice both answers equal 31,064,555
With that explanation out of the way, let's continue. Next, we take the number 31,064,555 and divide it by 2:
31,064,555 ÷ 2 = 15,532,277.5
If the quotient is a whole number, then 2 and 15,532,277.5 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 | 31,064,555 | |
| -1 | -31,064,555 |
Now, we try dividing 31,064,555 by 3:
31,064,555 ÷ 3 = 10,354,851.6667
If the quotient is a whole number, then 3 and 10,354,851.6667 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 | 31,064,555 | |
| -1 | -31,064,555 |
Let's try dividing by 4:
31,064,555 ÷ 4 = 7,766,138.75
If the quotient is a whole number, then 4 and 7,766,138.75 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 | 31,064,555 | |
| -1 | 31,064,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 179 | 305 | 569 | 895 | 2,845 | 10,919 | 34,709 | 54,595 | 101,851 | 173,545 | 509,255 | 6,212,911 | 31,064,555 |
| -1 | -5 | -61 | -179 | -305 | -569 | -895 | -2,845 | -10,919 | -34,709 | -54,595 | -101,851 | -173,545 | -509,255 | -6,212,911 | -31,064,555 |
