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 86,303,659, 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 | 86,303,659 | |
| -1 | -86,303,659 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 86,303,659.
Example:
1 x 86,303,659 = 86,303,659
and
-1 x -86,303,659 = 86,303,659
Notice both answers equal 86,303,659
With that explanation out of the way, let's continue. Next, we take the number 86,303,659 and divide it by 2:
86,303,659 ÷ 2 = 43,151,829.5
If the quotient is a whole number, then 2 and 43,151,829.5 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 | 86,303,659 | |
| -1 | -86,303,659 |
Now, we try dividing 86,303,659 by 3:
86,303,659 ÷ 3 = 28,767,886.3333
If the quotient is a whole number, then 3 and 28,767,886.3333 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 | 86,303,659 | |
| -1 | -86,303,659 |
Let's try dividing by 4:
86,303,659 ÷ 4 = 21,575,914.75
If the quotient is a whole number, then 4 and 21,575,914.75 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 | 86,303,659 | |
| -1 | 86,303,659 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 31 | 299 | 403 | 713 | 9,269 | 9,311 | 121,043 | 214,153 | 288,641 | 2,783,989 | 3,752,333 | 6,638,743 | 86,303,659 |
| -1 | -13 | -23 | -31 | -299 | -403 | -713 | -9,269 | -9,311 | -121,043 | -214,153 | -288,641 | -2,783,989 | -3,752,333 | -6,638,743 | -86,303,659 |
