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 7,622,363, 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 | 7,622,363 | |
| -1 | -7,622,363 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,622,363.
Example:
1 x 7,622,363 = 7,622,363
and
-1 x -7,622,363 = 7,622,363
Notice both answers equal 7,622,363
With that explanation out of the way, let's continue. Next, we take the number 7,622,363 and divide it by 2:
7,622,363 ÷ 2 = 3,811,181.5
If the quotient is a whole number, then 2 and 3,811,181.5 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 | 7,622,363 | |
| -1 | -7,622,363 |
Now, we try dividing 7,622,363 by 3:
7,622,363 ÷ 3 = 2,540,787.6667
If the quotient is a whole number, then 3 and 2,540,787.6667 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 | 7,622,363 | |
| -1 | -7,622,363 |
Let's try dividing by 4:
7,622,363 ÷ 4 = 1,905,590.75
If the quotient is a whole number, then 4 and 1,905,590.75 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 | 7,622,363 | |
| -1 | 7,622,363 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 223 | 257 | 1,561 | 1,799 | 4,237 | 4,883 | 29,659 | 34,181 | 57,311 | 401,177 | 1,088,909 | 7,622,363 |
| -1 | -7 | -19 | -133 | -223 | -257 | -1,561 | -1,799 | -4,237 | -4,883 | -29,659 | -34,181 | -57,311 | -401,177 | -1,088,909 | -7,622,363 |
