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 85,370,375, 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 | 85,370,375 | |
| -1 | -85,370,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 85,370,375.
Example:
1 x 85,370,375 = 85,370,375
and
-1 x -85,370,375 = 85,370,375
Notice both answers equal 85,370,375
With that explanation out of the way, let's continue. Next, we take the number 85,370,375 and divide it by 2:
85,370,375 ÷ 2 = 42,685,187.5
If the quotient is a whole number, then 2 and 42,685,187.5 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 | 85,370,375 | |
| -1 | -85,370,375 |
Now, we try dividing 85,370,375 by 3:
85,370,375 ÷ 3 = 28,456,791.6667
If the quotient is a whole number, then 3 and 28,456,791.6667 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 | 85,370,375 | |
| -1 | -85,370,375 |
Let's try dividing by 4:
85,370,375 ÷ 4 = 21,342,593.75
If the quotient is a whole number, then 4 and 21,342,593.75 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 | 85,370,375 | |
| -1 | 85,370,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 373 | 1,831 | 1,865 | 9,155 | 9,325 | 45,775 | 46,625 | 228,875 | 682,963 | 3,414,815 | 17,074,075 | 85,370,375 |
| -1 | -5 | -25 | -125 | -373 | -1,831 | -1,865 | -9,155 | -9,325 | -45,775 | -46,625 | -228,875 | -682,963 | -3,414,815 | -17,074,075 | -85,370,375 |
