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 10,858,393, 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 | 10,858,393 | |
| -1 | -10,858,393 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,858,393.
Example:
1 x 10,858,393 = 10,858,393
and
-1 x -10,858,393 = 10,858,393
Notice both answers equal 10,858,393
With that explanation out of the way, let's continue. Next, we take the number 10,858,393 and divide it by 2:
10,858,393 ÷ 2 = 5,429,196.5
If the quotient is a whole number, then 2 and 5,429,196.5 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 | 10,858,393 | |
| -1 | -10,858,393 |
Now, we try dividing 10,858,393 by 3:
10,858,393 ÷ 3 = 3,619,464.3333
If the quotient is a whole number, then 3 and 3,619,464.3333 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 | 10,858,393 | |
| -1 | -10,858,393 |
Let's try dividing by 4:
10,858,393 ÷ 4 = 2,714,598.25
If the quotient is a whole number, then 4 and 2,714,598.25 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 | 10,858,393 | |
| -1 | 10,858,393 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 91 | 119 | 221 | 1,547 | 7,019 | 49,133 | 91,247 | 119,323 | 638,729 | 835,261 | 1,551,199 | 10,858,393 |
| -1 | -7 | -13 | -17 | -91 | -119 | -221 | -1,547 | -7,019 | -49,133 | -91,247 | -119,323 | -638,729 | -835,261 | -1,551,199 | -10,858,393 |
