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 8,045,365, 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 | 8,045,365 | |
| -1 | -8,045,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,045,365.
Example:
1 x 8,045,365 = 8,045,365
and
-1 x -8,045,365 = 8,045,365
Notice both answers equal 8,045,365
With that explanation out of the way, let's continue. Next, we take the number 8,045,365 and divide it by 2:
8,045,365 ÷ 2 = 4,022,682.5
If the quotient is a whole number, then 2 and 4,022,682.5 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 | 8,045,365 | |
| -1 | -8,045,365 |
Now, we try dividing 8,045,365 by 3:
8,045,365 ÷ 3 = 2,681,788.3333
If the quotient is a whole number, then 3 and 2,681,788.3333 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 | 8,045,365 | |
| -1 | -8,045,365 |
Let's try dividing by 4:
8,045,365 ÷ 4 = 2,011,341.25
If the quotient is a whole number, then 4 and 2,011,341.25 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 | 8,045,365 | |
| -1 | 8,045,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 131 | 173 | 355 | 655 | 865 | 9,301 | 12,283 | 22,663 | 46,505 | 61,415 | 113,315 | 1,609,073 | 8,045,365 |
| -1 | -5 | -71 | -131 | -173 | -355 | -655 | -865 | -9,301 | -12,283 | -22,663 | -46,505 | -61,415 | -113,315 | -1,609,073 | -8,045,365 |
