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 7,031,575, 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 | 7,031,575 | |
| -1 | -7,031,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,031,575.
Example:
1 x 7,031,575 = 7,031,575
and
-1 x -7,031,575 = 7,031,575
Notice both answers equal 7,031,575
With that explanation out of the way, let's continue. Next, we take the number 7,031,575 and divide it by 2:
7,031,575 ÷ 2 = 3,515,787.5
If the quotient is a whole number, then 2 and 3,515,787.5 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 | 7,031,575 | |
| -1 | -7,031,575 |
Now, we try dividing 7,031,575 by 3:
7,031,575 ÷ 3 = 2,343,858.3333
If the quotient is a whole number, then 3 and 2,343,858.3333 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 | 7,031,575 | |
| -1 | -7,031,575 |
Let's try dividing by 4:
7,031,575 ÷ 4 = 1,757,893.75
If the quotient is a whole number, then 4 and 1,757,893.75 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 | 7,031,575 | |
| -1 | 7,031,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 43 | 155 | 211 | 215 | 775 | 1,055 | 1,075 | 1,333 | 5,275 | 6,541 | 6,665 | 9,073 | 32,705 | 33,325 | 45,365 | 163,525 | 226,825 | 281,263 | 1,406,315 | 7,031,575 |
| -1 | -5 | -25 | -31 | -43 | -155 | -211 | -215 | -775 | -1,055 | -1,075 | -1,333 | -5,275 | -6,541 | -6,665 | -9,073 | -32,705 | -33,325 | -45,365 | -163,525 | -226,825 | -281,263 | -1,406,315 | -7,031,575 |
