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 850,573,175, 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 | 850,573,175 | |
| -1 | -850,573,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 850,573,175.
Example:
1 x 850,573,175 = 850,573,175
and
-1 x -850,573,175 = 850,573,175
Notice both answers equal 850,573,175
With that explanation out of the way, let's continue. Next, we take the number 850,573,175 and divide it by 2:
850,573,175 ÷ 2 = 425,286,587.5
If the quotient is a whole number, then 2 and 425,286,587.5 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 | 850,573,175 | |
| -1 | -850,573,175 |
Now, we try dividing 850,573,175 by 3:
850,573,175 ÷ 3 = 283,524,391.6667
If the quotient is a whole number, then 3 and 283,524,391.6667 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 | 850,573,175 | |
| -1 | -850,573,175 |
Let's try dividing by 4:
850,573,175 ÷ 4 = 212,643,293.75
If the quotient is a whole number, then 4 and 212,643,293.75 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 | 850,573,175 | |
| -1 | 850,573,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 131 | 655 | 3,275 | 259,717 | 1,298,585 | 6,492,925 | 34,022,927 | 170,114,635 | 850,573,175 |
| -1 | -5 | -25 | -131 | -655 | -3,275 | -259,717 | -1,298,585 | -6,492,925 | -34,022,927 | -170,114,635 | -850,573,175 |
