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 85,052,429, 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 | 85,052,429 | |
| -1 | -85,052,429 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 85,052,429.
Example:
1 x 85,052,429 = 85,052,429
and
-1 x -85,052,429 = 85,052,429
Notice both answers equal 85,052,429
With that explanation out of the way, let's continue. Next, we take the number 85,052,429 and divide it by 2:
85,052,429 ÷ 2 = 42,526,214.5
If the quotient is a whole number, then 2 and 42,526,214.5 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 | 85,052,429 | |
| -1 | -85,052,429 |
Now, we try dividing 85,052,429 by 3:
85,052,429 ÷ 3 = 28,350,809.6667
If the quotient is a whole number, then 3 and 28,350,809.6667 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 | 85,052,429 | |
| -1 | -85,052,429 |
Let's try dividing by 4:
85,052,429 ÷ 4 = 21,263,107.25
If the quotient is a whole number, then 4 and 21,263,107.25 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 | 85,052,429 | |
| -1 | 85,052,429 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 313 | 2,191 | 3,443 | 3,529 | 24,101 | 24,703 | 38,819 | 271,733 | 1,104,577 | 7,732,039 | 12,150,347 | 85,052,429 |
| -1 | -7 | -11 | -77 | -313 | -2,191 | -3,443 | -3,529 | -24,101 | -24,703 | -38,819 | -271,733 | -1,104,577 | -7,732,039 | -12,150,347 | -85,052,429 |
