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 31,053,055, 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 | 31,053,055 | |
| -1 | -31,053,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,053,055.
Example:
1 x 31,053,055 = 31,053,055
and
-1 x -31,053,055 = 31,053,055
Notice both answers equal 31,053,055
With that explanation out of the way, let's continue. Next, we take the number 31,053,055 and divide it by 2:
31,053,055 ÷ 2 = 15,526,527.5
If the quotient is a whole number, then 2 and 15,526,527.5 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 | 31,053,055 | |
| -1 | -31,053,055 |
Now, we try dividing 31,053,055 by 3:
31,053,055 ÷ 3 = 10,351,018.3333
If the quotient is a whole number, then 3 and 10,351,018.3333 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 | 31,053,055 | |
| -1 | -31,053,055 |
Let's try dividing by 4:
31,053,055 ÷ 4 = 7,763,263.75
If the quotient is a whole number, then 4 and 7,763,263.75 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 | 31,053,055 | |
| -1 | 31,053,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 19,469 | 97,345 | 214,159 | 564,601 | 1,070,795 | 2,823,005 | 6,210,611 | 31,053,055 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -19,469 | -97,345 | -214,159 | -564,601 | -1,070,795 | -2,823,005 | -6,210,611 | -31,053,055 |
