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 1,336,139, 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 | 1,336,139 | |
| -1 | -1,336,139 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,336,139.
Example:
1 x 1,336,139 = 1,336,139
and
-1 x -1,336,139 = 1,336,139
Notice both answers equal 1,336,139
With that explanation out of the way, let's continue. Next, we take the number 1,336,139 and divide it by 2:
1,336,139 ÷ 2 = 668,069.5
If the quotient is a whole number, then 2 and 668,069.5 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 | 1,336,139 | |
| -1 | -1,336,139 |
Now, we try dividing 1,336,139 by 3:
1,336,139 ÷ 3 = 445,379.6667
If the quotient is a whole number, then 3 and 445,379.6667 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 | 1,336,139 | |
| -1 | -1,336,139 |
Let's try dividing by 4:
1,336,139 ÷ 4 = 334,034.75
If the quotient is a whole number, then 4 and 334,034.75 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 | 1,336,139 | |
| -1 | 1,336,139 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 43 | 161 | 193 | 301 | 989 | 1,351 | 4,439 | 6,923 | 8,299 | 31,073 | 58,093 | 190,877 | 1,336,139 |
| -1 | -7 | -23 | -43 | -161 | -193 | -301 | -989 | -1,351 | -4,439 | -6,923 | -8,299 | -31,073 | -58,093 | -190,877 | -1,336,139 |
