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 8,075,153, 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 | 8,075,153 | |
| -1 | -8,075,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,075,153.
Example:
1 x 8,075,153 = 8,075,153
and
-1 x -8,075,153 = 8,075,153
Notice both answers equal 8,075,153
With that explanation out of the way, let's continue. Next, we take the number 8,075,153 and divide it by 2:
8,075,153 ÷ 2 = 4,037,576.5
If the quotient is a whole number, then 2 and 4,037,576.5 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 | 8,075,153 | |
| -1 | -8,075,153 |
Now, we try dividing 8,075,153 by 3:
8,075,153 ÷ 3 = 2,691,717.6667
If the quotient is a whole number, then 3 and 2,691,717.6667 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 | 8,075,153 | |
| -1 | -8,075,153 |
Let's try dividing by 4:
8,075,153 ÷ 4 = 2,018,788.25
If the quotient is a whole number, then 4 and 2,018,788.25 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 | 8,075,153 | |
| -1 | 8,075,153 |
If you did it right, you will end up with this table:
| 1 | 17 | 59 | 83 | 97 | 1,003 | 1,411 | 1,649 | 4,897 | 5,723 | 8,051 | 83,249 | 97,291 | 136,867 | 475,009 | 8,075,153 |
| -1 | -17 | -59 | -83 | -97 | -1,003 | -1,411 | -1,649 | -4,897 | -5,723 | -8,051 | -83,249 | -97,291 | -136,867 | -475,009 | -8,075,153 |
