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 85,540,117, 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 | 85,540,117 | |
| -1 | -85,540,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 85,540,117.
Example:
1 x 85,540,117 = 85,540,117
and
-1 x -85,540,117 = 85,540,117
Notice both answers equal 85,540,117
With that explanation out of the way, let's continue. Next, we take the number 85,540,117 and divide it by 2:
85,540,117 ÷ 2 = 42,770,058.5
If the quotient is a whole number, then 2 and 42,770,058.5 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 | 85,540,117 | |
| -1 | -85,540,117 |
Now, we try dividing 85,540,117 by 3:
85,540,117 ÷ 3 = 28,513,372.3333
If the quotient is a whole number, then 3 and 28,513,372.3333 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 | 85,540,117 | |
| -1 | -85,540,117 |
Let's try dividing by 4:
85,540,117 ÷ 4 = 21,385,029.25
If the quotient is a whole number, then 4 and 21,385,029.25 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 | 85,540,117 | |
| -1 | 85,540,117 |
If you did it right, you will end up with this table:
| 1 | 13 | 61 | 269 | 401 | 793 | 3,497 | 5,213 | 16,409 | 24,461 | 107,869 | 213,317 | 317,993 | 1,402,297 | 6,580,009 | 85,540,117 |
| -1 | -13 | -61 | -269 | -401 | -793 | -3,497 | -5,213 | -16,409 | -24,461 | -107,869 | -213,317 | -317,993 | -1,402,297 | -6,580,009 | -85,540,117 |
