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 7,251,923, 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 | 7,251,923 | |
| -1 | -7,251,923 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,251,923.
Example:
1 x 7,251,923 = 7,251,923
and
-1 x -7,251,923 = 7,251,923
Notice both answers equal 7,251,923
With that explanation out of the way, let's continue. Next, we take the number 7,251,923 and divide it by 2:
7,251,923 ÷ 2 = 3,625,961.5
If the quotient is a whole number, then 2 and 3,625,961.5 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 | 7,251,923 | |
| -1 | -7,251,923 |
Now, we try dividing 7,251,923 by 3:
7,251,923 ÷ 3 = 2,417,307.6667
If the quotient is a whole number, then 3 and 2,417,307.6667 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 | 7,251,923 | |
| -1 | -7,251,923 |
Let's try dividing by 4:
7,251,923 ÷ 4 = 1,812,980.75
If the quotient is a whole number, then 4 and 1,812,980.75 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 | 7,251,923 | |
| -1 | 7,251,923 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 31 | 161 | 217 | 713 | 1,453 | 4,991 | 10,171 | 33,419 | 45,043 | 233,933 | 315,301 | 1,035,989 | 7,251,923 |
| -1 | -7 | -23 | -31 | -161 | -217 | -713 | -1,453 | -4,991 | -10,171 | -33,419 | -45,043 | -233,933 | -315,301 | -1,035,989 | -7,251,923 |
