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 84,258,601, 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 | 84,258,601 | |
| -1 | -84,258,601 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,258,601.
Example:
1 x 84,258,601 = 84,258,601
and
-1 x -84,258,601 = 84,258,601
Notice both answers equal 84,258,601
With that explanation out of the way, let's continue. Next, we take the number 84,258,601 and divide it by 2:
84,258,601 ÷ 2 = 42,129,300.5
If the quotient is a whole number, then 2 and 42,129,300.5 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 | 84,258,601 | |
| -1 | -84,258,601 |
Now, we try dividing 84,258,601 by 3:
84,258,601 ÷ 3 = 28,086,200.3333
If the quotient is a whole number, then 3 and 28,086,200.3333 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 | 84,258,601 | |
| -1 | -84,258,601 |
Let's try dividing by 4:
84,258,601 ÷ 4 = 21,064,650.25
If the quotient is a whole number, then 4 and 21,064,650.25 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 | 84,258,601 | |
| -1 | 84,258,601 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 269 | 1,543 | 1,883 | 7,801 | 10,801 | 44,747 | 54,607 | 313,229 | 415,067 | 2,905,469 | 12,036,943 | 84,258,601 |
| -1 | -7 | -29 | -203 | -269 | -1,543 | -1,883 | -7,801 | -10,801 | -44,747 | -54,607 | -313,229 | -415,067 | -2,905,469 | -12,036,943 | -84,258,601 |
