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 91,828,975, 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 | 91,828,975 | |
| -1 | -91,828,975 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 91,828,975.
Example:
1 x 91,828,975 = 91,828,975
and
-1 x -91,828,975 = 91,828,975
Notice both answers equal 91,828,975
With that explanation out of the way, let's continue. Next, we take the number 91,828,975 and divide it by 2:
91,828,975 ÷ 2 = 45,914,487.5
If the quotient is a whole number, then 2 and 45,914,487.5 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 | 91,828,975 | |
| -1 | -91,828,975 |
Now, we try dividing 91,828,975 by 3:
91,828,975 ÷ 3 = 30,609,658.3333
If the quotient is a whole number, then 3 and 30,609,658.3333 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 | 91,828,975 | |
| -1 | -91,828,975 |
Let's try dividing by 4:
91,828,975 ÷ 4 = 22,957,243.75
If the quotient is a whole number, then 4 and 22,957,243.75 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 | 91,828,975 | |
| -1 | 91,828,975 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 31 | 35 | 155 | 175 | 217 | 775 | 1,085 | 5,425 | 16,927 | 84,635 | 118,489 | 423,175 | 524,737 | 592,445 | 2,623,685 | 2,962,225 | 3,673,159 | 13,118,425 | 18,365,795 | 91,828,975 |
| -1 | -5 | -7 | -25 | -31 | -35 | -155 | -175 | -217 | -775 | -1,085 | -5,425 | -16,927 | -84,635 | -118,489 | -423,175 | -524,737 | -592,445 | -2,623,685 | -2,962,225 | -3,673,159 | -13,118,425 | -18,365,795 | -91,828,975 |
