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 7,435,897, 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 | 7,435,897 | |
| -1 | -7,435,897 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,435,897.
Example:
1 x 7,435,897 = 7,435,897
and
-1 x -7,435,897 = 7,435,897
Notice both answers equal 7,435,897
With that explanation out of the way, let's continue. Next, we take the number 7,435,897 and divide it by 2:
7,435,897 ÷ 2 = 3,717,948.5
If the quotient is a whole number, then 2 and 3,717,948.5 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 | 7,435,897 | |
| -1 | -7,435,897 |
Now, we try dividing 7,435,897 by 3:
7,435,897 ÷ 3 = 2,478,632.3333
If the quotient is a whole number, then 3 and 2,478,632.3333 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 | 7,435,897 | |
| -1 | -7,435,897 |
Let's try dividing by 4:
7,435,897 ÷ 4 = 1,858,974.25
If the quotient is a whole number, then 4 and 1,858,974.25 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 | 7,435,897 | |
| -1 | 7,435,897 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 49 | 133 | 163 | 343 | 931 | 1,141 | 2,401 | 3,097 | 6,517 | 7,987 | 21,679 | 45,619 | 55,909 | 151,753 | 391,363 | 1,062,271 | 7,435,897 |
| -1 | -7 | -19 | -49 | -133 | -163 | -343 | -931 | -1,141 | -2,401 | -3,097 | -6,517 | -7,987 | -21,679 | -45,619 | -55,909 | -151,753 | -391,363 | -1,062,271 | -7,435,897 |
