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 22,045,247, 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 | 22,045,247 | |
| -1 | -22,045,247 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,045,247.
Example:
1 x 22,045,247 = 22,045,247
and
-1 x -22,045,247 = 22,045,247
Notice both answers equal 22,045,247
With that explanation out of the way, let's continue. Next, we take the number 22,045,247 and divide it by 2:
22,045,247 ÷ 2 = 11,022,623.5
If the quotient is a whole number, then 2 and 11,022,623.5 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 | 22,045,247 | |
| -1 | -22,045,247 |
Now, we try dividing 22,045,247 by 3:
22,045,247 ÷ 3 = 7,348,415.6667
If the quotient is a whole number, then 3 and 7,348,415.6667 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 | 22,045,247 | |
| -1 | -22,045,247 |
Let's try dividing by 4:
22,045,247 ÷ 4 = 5,511,311.75
If the quotient is a whole number, then 4 and 5,511,311.75 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 | 22,045,247 | |
| -1 | 22,045,247 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 31 | 49 | 161 | 217 | 631 | 713 | 1,127 | 1,519 | 4,417 | 4,991 | 14,513 | 19,561 | 30,919 | 34,937 | 101,591 | 136,927 | 449,903 | 711,137 | 958,489 | 3,149,321 | 22,045,247 |
| -1 | -7 | -23 | -31 | -49 | -161 | -217 | -631 | -713 | -1,127 | -1,519 | -4,417 | -4,991 | -14,513 | -19,561 | -30,919 | -34,937 | -101,591 | -136,927 | -449,903 | -711,137 | -958,489 | -3,149,321 | -22,045,247 |
