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 7,623,427, 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 | 7,623,427 | |
| -1 | -7,623,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,623,427.
Example:
1 x 7,623,427 = 7,623,427
and
-1 x -7,623,427 = 7,623,427
Notice both answers equal 7,623,427
With that explanation out of the way, let's continue. Next, we take the number 7,623,427 and divide it by 2:
7,623,427 ÷ 2 = 3,811,713.5
If the quotient is a whole number, then 2 and 3,811,713.5 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 | 7,623,427 | |
| -1 | -7,623,427 |
Now, we try dividing 7,623,427 by 3:
7,623,427 ÷ 3 = 2,541,142.3333
If the quotient is a whole number, then 3 and 2,541,142.3333 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 | 7,623,427 | |
| -1 | -7,623,427 |
Let's try dividing by 4:
7,623,427 ÷ 4 = 1,905,856.75
If the quotient is a whole number, then 4 and 1,905,856.75 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 | 7,623,427 | |
| -1 | 7,623,427 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 31 | 43 | 133 | 217 | 301 | 589 | 817 | 1,333 | 1,849 | 4,123 | 5,719 | 9,331 | 12,943 | 25,327 | 35,131 | 57,319 | 177,289 | 245,917 | 401,233 | 1,089,061 | 7,623,427 |
| -1 | -7 | -19 | -31 | -43 | -133 | -217 | -301 | -589 | -817 | -1,333 | -1,849 | -4,123 | -5,719 | -9,331 | -12,943 | -25,327 | -35,131 | -57,319 | -177,289 | -245,917 | -401,233 | -1,089,061 | -7,623,427 |
