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 4,692,221, 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 | 4,692,221 | |
| -1 | -4,692,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,692,221.
Example:
1 x 4,692,221 = 4,692,221
and
-1 x -4,692,221 = 4,692,221
Notice both answers equal 4,692,221
With that explanation out of the way, let's continue. Next, we take the number 4,692,221 and divide it by 2:
4,692,221 ÷ 2 = 2,346,110.5
If the quotient is a whole number, then 2 and 2,346,110.5 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 | 4,692,221 | |
| -1 | -4,692,221 |
Now, we try dividing 4,692,221 by 3:
4,692,221 ÷ 3 = 1,564,073.6667
If the quotient is a whole number, then 3 and 1,564,073.6667 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 | 4,692,221 | |
| -1 | -4,692,221 |
Let's try dividing by 4:
4,692,221 ÷ 4 = 1,173,055.25
If the quotient is a whole number, then 4 and 1,173,055.25 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 | 4,692,221 | |
| -1 | 4,692,221 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 73 | 199 | 323 | 1,241 | 1,387 | 3,383 | 3,781 | 14,527 | 23,579 | 64,277 | 246,959 | 276,013 | 4,692,221 |
| -1 | -17 | -19 | -73 | -199 | -323 | -1,241 | -1,387 | -3,383 | -3,781 | -14,527 | -23,579 | -64,277 | -246,959 | -276,013 | -4,692,221 |
