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 74,083,585, 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 | 74,083,585 | |
| -1 | -74,083,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,083,585.
Example:
1 x 74,083,585 = 74,083,585
and
-1 x -74,083,585 = 74,083,585
Notice both answers equal 74,083,585
With that explanation out of the way, let's continue. Next, we take the number 74,083,585 and divide it by 2:
74,083,585 ÷ 2 = 37,041,792.5
If the quotient is a whole number, then 2 and 37,041,792.5 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 | 74,083,585 | |
| -1 | -74,083,585 |
Now, we try dividing 74,083,585 by 3:
74,083,585 ÷ 3 = 24,694,528.3333
If the quotient is a whole number, then 3 and 24,694,528.3333 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 | 74,083,585 | |
| -1 | -74,083,585 |
Let's try dividing by 4:
74,083,585 ÷ 4 = 18,520,896.25
If the quotient is a whole number, then 4 and 18,520,896.25 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 | 74,083,585 | |
| -1 | 74,083,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 293 | 305 | 829 | 1,465 | 4,145 | 17,873 | 50,569 | 89,365 | 242,897 | 252,845 | 1,214,485 | 14,816,717 | 74,083,585 |
| -1 | -5 | -61 | -293 | -305 | -829 | -1,465 | -4,145 | -17,873 | -50,569 | -89,365 | -242,897 | -252,845 | -1,214,485 | -14,816,717 | -74,083,585 |
