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 35,090,783, 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 | 35,090,783 | |
| -1 | -35,090,783 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,090,783.
Example:
1 x 35,090,783 = 35,090,783
and
-1 x -35,090,783 = 35,090,783
Notice both answers equal 35,090,783
With that explanation out of the way, let's continue. Next, we take the number 35,090,783 and divide it by 2:
35,090,783 ÷ 2 = 17,545,391.5
If the quotient is a whole number, then 2 and 17,545,391.5 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 | 35,090,783 | |
| -1 | -35,090,783 |
Now, we try dividing 35,090,783 by 3:
35,090,783 ÷ 3 = 11,696,927.6667
If the quotient is a whole number, then 3 and 11,696,927.6667 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 | 35,090,783 | |
| -1 | -35,090,783 |
Let's try dividing by 4:
35,090,783 ÷ 4 = 8,772,695.75
If the quotient is a whole number, then 4 and 8,772,695.75 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 | 35,090,783 | |
| -1 | 35,090,783 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 29 | 91 | 203 | 377 | 2,639 | 13,297 | 93,079 | 172,861 | 385,613 | 1,210,027 | 2,699,291 | 5,012,969 | 35,090,783 |
| -1 | -7 | -13 | -29 | -91 | -203 | -377 | -2,639 | -13,297 | -93,079 | -172,861 | -385,613 | -1,210,027 | -2,699,291 | -5,012,969 | -35,090,783 |
