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 182,613,031, 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 | 182,613,031 | |
| -1 | -182,613,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 182,613,031.
Example:
1 x 182,613,031 = 182,613,031
and
-1 x -182,613,031 = 182,613,031
Notice both answers equal 182,613,031
With that explanation out of the way, let's continue. Next, we take the number 182,613,031 and divide it by 2:
182,613,031 ÷ 2 = 91,306,515.5
If the quotient is a whole number, then 2 and 91,306,515.5 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 | 182,613,031 | |
| -1 | -182,613,031 |
Now, we try dividing 182,613,031 by 3:
182,613,031 ÷ 3 = 60,871,010.3333
If the quotient is a whole number, then 3 and 60,871,010.3333 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 | 182,613,031 | |
| -1 | -182,613,031 |
Let's try dividing by 4:
182,613,031 ÷ 4 = 45,653,257.75
If the quotient is a whole number, then 4 and 45,653,257.75 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 | 182,613,031 | |
| -1 | 182,613,031 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 83 | 289 | 331 | 391 | 1,411 | 1,909 | 5,627 | 6,647 | 7,613 | 23,987 | 27,473 | 32,453 | 95,659 | 129,421 | 467,041 | 551,701 | 631,879 | 2,200,157 | 7,939,697 | 10,741,943 | 182,613,031 |
| -1 | -17 | -23 | -83 | -289 | -331 | -391 | -1,411 | -1,909 | -5,627 | -6,647 | -7,613 | -23,987 | -27,473 | -32,453 | -95,659 | -129,421 | -467,041 | -551,701 | -631,879 | -2,200,157 | -7,939,697 | -10,741,943 | -182,613,031 |
