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 2,356,991, 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 | 2,356,991 | |
| -1 | -2,356,991 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,356,991.
Example:
1 x 2,356,991 = 2,356,991
and
-1 x -2,356,991 = 2,356,991
Notice both answers equal 2,356,991
With that explanation out of the way, let's continue. Next, we take the number 2,356,991 and divide it by 2:
2,356,991 ÷ 2 = 1,178,495.5
If the quotient is a whole number, then 2 and 1,178,495.5 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 | 2,356,991 | |
| -1 | -2,356,991 |
Now, we try dividing 2,356,991 by 3:
2,356,991 ÷ 3 = 785,663.6667
If the quotient is a whole number, then 3 and 785,663.6667 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 | 2,356,991 | |
| -1 | -2,356,991 |
Let's try dividing by 4:
2,356,991 ÷ 4 = 589,247.75
If the quotient is a whole number, then 4 and 589,247.75 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 | 2,356,991 | |
| -1 | 2,356,991 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 59 | 91 | 413 | 439 | 767 | 3,073 | 5,369 | 5,707 | 25,901 | 39,949 | 181,307 | 336,713 | 2,356,991 |
| -1 | -7 | -13 | -59 | -91 | -413 | -439 | -767 | -3,073 | -5,369 | -5,707 | -25,901 | -39,949 | -181,307 | -336,713 | -2,356,991 |
