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 18,600,673, 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 | 18,600,673 | |
| -1 | -18,600,673 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,600,673.
Example:
1 x 18,600,673 = 18,600,673
and
-1 x -18,600,673 = 18,600,673
Notice both answers equal 18,600,673
With that explanation out of the way, let's continue. Next, we take the number 18,600,673 and divide it by 2:
18,600,673 ÷ 2 = 9,300,336.5
If the quotient is a whole number, then 2 and 9,300,336.5 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 | 18,600,673 | |
| -1 | -18,600,673 |
Now, we try dividing 18,600,673 by 3:
18,600,673 ÷ 3 = 6,200,224.3333
If the quotient is a whole number, then 3 and 6,200,224.3333 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 | 18,600,673 | |
| -1 | -18,600,673 |
Let's try dividing by 4:
18,600,673 ÷ 4 = 4,650,168.25
If the quotient is a whole number, then 4 and 4,650,168.25 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 | 18,600,673 | |
| -1 | 18,600,673 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 47 | 91 | 329 | 611 | 4,277 | 4,349 | 30,443 | 56,537 | 204,403 | 395,759 | 1,430,821 | 2,657,239 | 18,600,673 |
| -1 | -7 | -13 | -47 | -91 | -329 | -611 | -4,277 | -4,349 | -30,443 | -56,537 | -204,403 | -395,759 | -1,430,821 | -2,657,239 | -18,600,673 |
