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 85,150,345, 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 | 85,150,345 | |
| -1 | -85,150,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 85,150,345.
Example:
1 x 85,150,345 = 85,150,345
and
-1 x -85,150,345 = 85,150,345
Notice both answers equal 85,150,345
With that explanation out of the way, let's continue. Next, we take the number 85,150,345 and divide it by 2:
85,150,345 ÷ 2 = 42,575,172.5
If the quotient is a whole number, then 2 and 42,575,172.5 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 | 85,150,345 | |
| -1 | -85,150,345 |
Now, we try dividing 85,150,345 by 3:
85,150,345 ÷ 3 = 28,383,448.3333
If the quotient is a whole number, then 3 and 28,383,448.3333 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 | 85,150,345 | |
| -1 | -85,150,345 |
Let's try dividing by 4:
85,150,345 ÷ 4 = 21,287,586.25
If the quotient is a whole number, then 4 and 21,287,586.25 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 | 85,150,345 | |
| -1 | 85,150,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 401 | 2,005 | 2,807 | 6,067 | 14,035 | 30,335 | 42,469 | 212,345 | 2,432,867 | 12,164,335 | 17,030,069 | 85,150,345 |
| -1 | -5 | -7 | -35 | -401 | -2,005 | -2,807 | -6,067 | -14,035 | -30,335 | -42,469 | -212,345 | -2,432,867 | -12,164,335 | -17,030,069 | -85,150,345 |
