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 7,606,291, 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 | 7,606,291 | |
| -1 | -7,606,291 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,606,291.
Example:
1 x 7,606,291 = 7,606,291
and
-1 x -7,606,291 = 7,606,291
Notice both answers equal 7,606,291
With that explanation out of the way, let's continue. Next, we take the number 7,606,291 and divide it by 2:
7,606,291 ÷ 2 = 3,803,145.5
If the quotient is a whole number, then 2 and 3,803,145.5 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 | 7,606,291 | |
| -1 | -7,606,291 |
Now, we try dividing 7,606,291 by 3:
7,606,291 ÷ 3 = 2,535,430.3333
If the quotient is a whole number, then 3 and 2,535,430.3333 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 | 7,606,291 | |
| -1 | -7,606,291 |
Let's try dividing by 4:
7,606,291 ÷ 4 = 1,901,572.75
If the quotient is a whole number, then 4 and 1,901,572.75 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 | 7,606,291 | |
| -1 | 7,606,291 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 173 | 571 | 1,211 | 1,903 | 3,997 | 6,281 | 13,321 | 43,967 | 98,783 | 691,481 | 1,086,613 | 7,606,291 |
| -1 | -7 | -11 | -77 | -173 | -571 | -1,211 | -1,903 | -3,997 | -6,281 | -13,321 | -43,967 | -98,783 | -691,481 | -1,086,613 | -7,606,291 |
