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 7,526,071, 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 | 7,526,071 | |
| -1 | -7,526,071 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,526,071.
Example:
1 x 7,526,071 = 7,526,071
and
-1 x -7,526,071 = 7,526,071
Notice both answers equal 7,526,071
With that explanation out of the way, let's continue. Next, we take the number 7,526,071 and divide it by 2:
7,526,071 ÷ 2 = 3,763,035.5
If the quotient is a whole number, then 2 and 3,763,035.5 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 | 7,526,071 | |
| -1 | -7,526,071 |
Now, we try dividing 7,526,071 by 3:
7,526,071 ÷ 3 = 2,508,690.3333
If the quotient is a whole number, then 3 and 2,508,690.3333 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 | 7,526,071 | |
| -1 | -7,526,071 |
Let's try dividing by 4:
7,526,071 ÷ 4 = 1,881,517.75
If the quotient is a whole number, then 4 and 1,881,517.75 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 | 7,526,071 | |
| -1 | 7,526,071 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 71 | 133 | 497 | 797 | 1,349 | 5,579 | 9,443 | 15,143 | 56,587 | 106,001 | 396,109 | 1,075,153 | 7,526,071 |
| -1 | -7 | -19 | -71 | -133 | -497 | -797 | -1,349 | -5,579 | -9,443 | -15,143 | -56,587 | -106,001 | -396,109 | -1,075,153 | -7,526,071 |
