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 91,850,825, 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 | 91,850,825 | |
| -1 | -91,850,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 91,850,825.
Example:
1 x 91,850,825 = 91,850,825
and
-1 x -91,850,825 = 91,850,825
Notice both answers equal 91,850,825
With that explanation out of the way, let's continue. Next, we take the number 91,850,825 and divide it by 2:
91,850,825 ÷ 2 = 45,925,412.5
If the quotient is a whole number, then 2 and 45,925,412.5 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 | 91,850,825 | |
| -1 | -91,850,825 |
Now, we try dividing 91,850,825 by 3:
91,850,825 ÷ 3 = 30,616,941.6667
If the quotient is a whole number, then 3 and 30,616,941.6667 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 | 91,850,825 | |
| -1 | -91,850,825 |
Let's try dividing by 4:
91,850,825 ÷ 4 = 22,962,706.25
If the quotient is a whole number, then 4 and 22,962,706.25 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 | 91,850,825 | |
| -1 | 91,850,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 275 | 569 | 587 | 2,845 | 2,935 | 6,259 | 6,457 | 14,225 | 14,675 | 31,295 | 32,285 | 156,475 | 161,425 | 334,003 | 1,670,015 | 3,674,033 | 8,350,075 | 18,370,165 | 91,850,825 |
| -1 | -5 | -11 | -25 | -55 | -275 | -569 | -587 | -2,845 | -2,935 | -6,259 | -6,457 | -14,225 | -14,675 | -31,295 | -32,285 | -156,475 | -161,425 | -334,003 | -1,670,015 | -3,674,033 | -8,350,075 | -18,370,165 | -91,850,825 |
