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 35,320,663, 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 | 35,320,663 | |
| -1 | -35,320,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,320,663.
Example:
1 x 35,320,663 = 35,320,663
and
-1 x -35,320,663 = 35,320,663
Notice both answers equal 35,320,663
With that explanation out of the way, let's continue. Next, we take the number 35,320,663 and divide it by 2:
35,320,663 ÷ 2 = 17,660,331.5
If the quotient is a whole number, then 2 and 17,660,331.5 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 | 35,320,663 | |
| -1 | -35,320,663 |
Now, we try dividing 35,320,663 by 3:
35,320,663 ÷ 3 = 11,773,554.3333
If the quotient is a whole number, then 3 and 11,773,554.3333 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 | 35,320,663 | |
| -1 | -35,320,663 |
Let's try dividing by 4:
35,320,663 ÷ 4 = 8,830,165.75
If the quotient is a whole number, then 4 and 8,830,165.75 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 | 35,320,663 | |
| -1 | 35,320,663 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 79 | 161 | 553 | 1,817 | 2,777 | 12,719 | 19,439 | 63,871 | 219,383 | 447,097 | 1,535,681 | 5,045,809 | 35,320,663 |
| -1 | -7 | -23 | -79 | -161 | -553 | -1,817 | -2,777 | -12,719 | -19,439 | -63,871 | -219,383 | -447,097 | -1,535,681 | -5,045,809 | -35,320,663 |
