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 35,315,765, 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 | 35,315,765 | |
| -1 | -35,315,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,315,765.
Example:
1 x 35,315,765 = 35,315,765
and
-1 x -35,315,765 = 35,315,765
Notice both answers equal 35,315,765
With that explanation out of the way, let's continue. Next, we take the number 35,315,765 and divide it by 2:
35,315,765 ÷ 2 = 17,657,882.5
If the quotient is a whole number, then 2 and 17,657,882.5 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 | 35,315,765 | |
| -1 | -35,315,765 |
Now, we try dividing 35,315,765 by 3:
35,315,765 ÷ 3 = 11,771,921.6667
If the quotient is a whole number, then 3 and 11,771,921.6667 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 | 35,315,765 | |
| -1 | -35,315,765 |
Let's try dividing by 4:
35,315,765 ÷ 4 = 8,828,941.25
If the quotient is a whole number, then 4 and 8,828,941.25 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 | 35,315,765 | |
| -1 | 35,315,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 79 | 145 | 395 | 2,291 | 3,083 | 11,455 | 15,415 | 89,407 | 243,557 | 447,035 | 1,217,785 | 7,063,153 | 35,315,765 |
| -1 | -5 | -29 | -79 | -145 | -395 | -2,291 | -3,083 | -11,455 | -15,415 | -89,407 | -243,557 | -447,035 | -1,217,785 | -7,063,153 | -35,315,765 |
