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 94,702,517, 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 | 94,702,517 | |
| -1 | -94,702,517 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 94,702,517.
Example:
1 x 94,702,517 = 94,702,517
and
-1 x -94,702,517 = 94,702,517
Notice both answers equal 94,702,517
With that explanation out of the way, let's continue. Next, we take the number 94,702,517 and divide it by 2:
94,702,517 ÷ 2 = 47,351,258.5
If the quotient is a whole number, then 2 and 47,351,258.5 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 | 94,702,517 | |
| -1 | -94,702,517 |
Now, we try dividing 94,702,517 by 3:
94,702,517 ÷ 3 = 31,567,505.6667
If the quotient is a whole number, then 3 and 31,567,505.6667 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 | 94,702,517 | |
| -1 | -94,702,517 |
Let's try dividing by 4:
94,702,517 ÷ 4 = 23,675,629.25
If the quotient is a whole number, then 4 and 23,675,629.25 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 | 94,702,517 | |
| -1 | 94,702,517 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 19 | 91 | 133 | 247 | 1,729 | 54,773 | 383,411 | 712,049 | 1,040,687 | 4,984,343 | 7,284,809 | 13,528,931 | 94,702,517 |
| -1 | -7 | -13 | -19 | -91 | -133 | -247 | -1,729 | -54,773 | -383,411 | -712,049 | -1,040,687 | -4,984,343 | -7,284,809 | -13,528,931 | -94,702,517 |
