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 83,051,717, 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 | 83,051,717 | |
| -1 | -83,051,717 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,051,717.
Example:
1 x 83,051,717 = 83,051,717
and
-1 x -83,051,717 = 83,051,717
Notice both answers equal 83,051,717
With that explanation out of the way, let's continue. Next, we take the number 83,051,717 and divide it by 2:
83,051,717 ÷ 2 = 41,525,858.5
If the quotient is a whole number, then 2 and 41,525,858.5 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 | 83,051,717 | |
| -1 | -83,051,717 |
Now, we try dividing 83,051,717 by 3:
83,051,717 ÷ 3 = 27,683,905.6667
If the quotient is a whole number, then 3 and 27,683,905.6667 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 | 83,051,717 | |
| -1 | -83,051,717 |
Let's try dividing by 4:
83,051,717 ÷ 4 = 20,762,929.25
If the quotient is a whole number, then 4 and 20,762,929.25 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 | 83,051,717 | |
| -1 | 83,051,717 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 37 | 49 | 133 | 259 | 703 | 931 | 1,813 | 2,411 | 4,921 | 16,877 | 34,447 | 45,809 | 89,207 | 118,139 | 320,663 | 624,449 | 1,694,933 | 2,244,641 | 4,371,143 | 11,864,531 | 83,051,717 |
| -1 | -7 | -19 | -37 | -49 | -133 | -259 | -703 | -931 | -1,813 | -2,411 | -4,921 | -16,877 | -34,447 | -45,809 | -89,207 | -118,139 | -320,663 | -624,449 | -1,694,933 | -2,244,641 | -4,371,143 | -11,864,531 | -83,051,717 |
