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 18,630,667, 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 | 18,630,667 | |
| -1 | -18,630,667 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,630,667.
Example:
1 x 18,630,667 = 18,630,667
and
-1 x -18,630,667 = 18,630,667
Notice both answers equal 18,630,667
With that explanation out of the way, let's continue. Next, we take the number 18,630,667 and divide it by 2:
18,630,667 ÷ 2 = 9,315,333.5
If the quotient is a whole number, then 2 and 9,315,333.5 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 | 18,630,667 | |
| -1 | -18,630,667 |
Now, we try dividing 18,630,667 by 3:
18,630,667 ÷ 3 = 6,210,222.3333
If the quotient is a whole number, then 3 and 6,210,222.3333 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 | 18,630,667 | |
| -1 | -18,630,667 |
Let's try dividing by 4:
18,630,667 ÷ 4 = 4,657,666.75
If the quotient is a whole number, then 4 and 4,657,666.75 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 | 18,630,667 | |
| -1 | 18,630,667 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 211 | 253 | 349 | 2,321 | 3,839 | 4,853 | 8,027 | 53,383 | 73,639 | 88,297 | 810,029 | 1,693,697 | 18,630,667 |
| -1 | -11 | -23 | -211 | -253 | -349 | -2,321 | -3,839 | -4,853 | -8,027 | -53,383 | -73,639 | -88,297 | -810,029 | -1,693,697 | -18,630,667 |
