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 7,142,737, 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 | 7,142,737 | |
| -1 | -7,142,737 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,142,737.
Example:
1 x 7,142,737 = 7,142,737
and
-1 x -7,142,737 = 7,142,737
Notice both answers equal 7,142,737
With that explanation out of the way, let's continue. Next, we take the number 7,142,737 and divide it by 2:
7,142,737 ÷ 2 = 3,571,368.5
If the quotient is a whole number, then 2 and 3,571,368.5 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 | 7,142,737 | |
| -1 | -7,142,737 |
Now, we try dividing 7,142,737 by 3:
7,142,737 ÷ 3 = 2,380,912.3333
If the quotient is a whole number, then 3 and 2,380,912.3333 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 | 7,142,737 | |
| -1 | -7,142,737 |
Let's try dividing by 4:
7,142,737 ÷ 4 = 1,785,684.25
If the quotient is a whole number, then 4 and 1,785,684.25 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 | 7,142,737 | |
| -1 | 7,142,737 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 193 | 311 | 1,351 | 2,177 | 3,281 | 5,287 | 22,967 | 37,009 | 60,023 | 420,161 | 1,020,391 | 7,142,737 |
| -1 | -7 | -17 | -119 | -193 | -311 | -1,351 | -2,177 | -3,281 | -5,287 | -22,967 | -37,009 | -60,023 | -420,161 | -1,020,391 | -7,142,737 |
