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 8,151,269, 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 | 8,151,269 | |
| -1 | -8,151,269 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,151,269.
Example:
1 x 8,151,269 = 8,151,269
and
-1 x -8,151,269 = 8,151,269
Notice both answers equal 8,151,269
With that explanation out of the way, let's continue. Next, we take the number 8,151,269 and divide it by 2:
8,151,269 ÷ 2 = 4,075,634.5
If the quotient is a whole number, then 2 and 4,075,634.5 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 | 8,151,269 | |
| -1 | -8,151,269 |
Now, we try dividing 8,151,269 by 3:
8,151,269 ÷ 3 = 2,717,089.6667
If the quotient is a whole number, then 3 and 2,717,089.6667 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 | 8,151,269 | |
| -1 | -8,151,269 |
Let's try dividing by 4:
8,151,269 ÷ 4 = 2,037,817.25
If the quotient is a whole number, then 4 and 2,037,817.25 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 | 8,151,269 | |
| -1 | 8,151,269 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 197 | 257 | 1,379 | 1,799 | 4,531 | 5,911 | 31,717 | 41,377 | 50,629 | 354,403 | 1,164,467 | 8,151,269 |
| -1 | -7 | -23 | -161 | -197 | -257 | -1,379 | -1,799 | -4,531 | -5,911 | -31,717 | -41,377 | -50,629 | -354,403 | -1,164,467 | -8,151,269 |
