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 22,314,551, 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 | 22,314,551 | |
| -1 | -22,314,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,314,551.
Example:
1 x 22,314,551 = 22,314,551
and
-1 x -22,314,551 = 22,314,551
Notice both answers equal 22,314,551
With that explanation out of the way, let's continue. Next, we take the number 22,314,551 and divide it by 2:
22,314,551 ÷ 2 = 11,157,275.5
If the quotient is a whole number, then 2 and 11,157,275.5 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 | 22,314,551 | |
| -1 | -22,314,551 |
Now, we try dividing 22,314,551 by 3:
22,314,551 ÷ 3 = 7,438,183.6667
If the quotient is a whole number, then 3 and 7,438,183.6667 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 | 22,314,551 | |
| -1 | -22,314,551 |
Let's try dividing by 4:
22,314,551 ÷ 4 = 5,578,637.75
If the quotient is a whole number, then 4 and 5,578,637.75 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 | 22,314,551 | |
| -1 | 22,314,551 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 67 | 343 | 469 | 971 | 3,283 | 6,797 | 22,981 | 47,579 | 65,057 | 333,053 | 455,399 | 3,187,793 | 22,314,551 |
| -1 | -7 | -49 | -67 | -343 | -469 | -971 | -3,283 | -6,797 | -22,981 | -47,579 | -65,057 | -333,053 | -455,399 | -3,187,793 | -22,314,551 |
