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 45,216,017, 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 | 45,216,017 | |
| -1 | -45,216,017 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,216,017.
Example:
1 x 45,216,017 = 45,216,017
and
-1 x -45,216,017 = 45,216,017
Notice both answers equal 45,216,017
With that explanation out of the way, let's continue. Next, we take the number 45,216,017 and divide it by 2:
45,216,017 ÷ 2 = 22,608,008.5
If the quotient is a whole number, then 2 and 22,608,008.5 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 | 45,216,017 | |
| -1 | -45,216,017 |
Now, we try dividing 45,216,017 by 3:
45,216,017 ÷ 3 = 15,072,005.6667
If the quotient is a whole number, then 3 and 15,072,005.6667 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 | 45,216,017 | |
| -1 | -45,216,017 |
Let's try dividing by 4:
45,216,017 ÷ 4 = 11,304,004.25
If the quotient is a whole number, then 4 and 11,304,004.25 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 | 45,216,017 | |
| -1 | 45,216,017 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 29 | 77 | 203 | 319 | 2,233 | 20,249 | 141,743 | 222,739 | 587,221 | 1,559,173 | 4,110,547 | 6,459,431 | 45,216,017 |
| -1 | -7 | -11 | -29 | -77 | -203 | -319 | -2,233 | -20,249 | -141,743 | -222,739 | -587,221 | -1,559,173 | -4,110,547 | -6,459,431 | -45,216,017 |
