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 83,468,645, 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 | 83,468,645 | |
| -1 | -83,468,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,468,645.
Example:
1 x 83,468,645 = 83,468,645
and
-1 x -83,468,645 = 83,468,645
Notice both answers equal 83,468,645
With that explanation out of the way, let's continue. Next, we take the number 83,468,645 and divide it by 2:
83,468,645 ÷ 2 = 41,734,322.5
If the quotient is a whole number, then 2 and 41,734,322.5 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 | 83,468,645 | |
| -1 | -83,468,645 |
Now, we try dividing 83,468,645 by 3:
83,468,645 ÷ 3 = 27,822,881.6667
If the quotient is a whole number, then 3 and 27,822,881.6667 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 | 83,468,645 | |
| -1 | -83,468,645 |
Let's try dividing by 4:
83,468,645 ÷ 4 = 20,867,161.25
If the quotient is a whole number, then 4 and 20,867,161.25 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 | 83,468,645 | |
| -1 | 83,468,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 367 | 1,835 | 3,499 | 4,771 | 17,495 | 23,855 | 45,487 | 227,435 | 1,284,133 | 6,420,665 | 16,693,729 | 83,468,645 |
| -1 | -5 | -13 | -65 | -367 | -1,835 | -3,499 | -4,771 | -17,495 | -23,855 | -45,487 | -227,435 | -1,284,133 | -6,420,665 | -16,693,729 | -83,468,645 |
