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 1,301,195, 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 | 1,301,195 | |
| -1 | -1,301,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,301,195.
Example:
1 x 1,301,195 = 1,301,195
and
-1 x -1,301,195 = 1,301,195
Notice both answers equal 1,301,195
With that explanation out of the way, let's continue. Next, we take the number 1,301,195 and divide it by 2:
1,301,195 ÷ 2 = 650,597.5
If the quotient is a whole number, then 2 and 650,597.5 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 | 1,301,195 | |
| -1 | -1,301,195 |
Now, we try dividing 1,301,195 by 3:
1,301,195 ÷ 3 = 433,731.6667
If the quotient is a whole number, then 3 and 433,731.6667 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 | 1,301,195 | |
| -1 | -1,301,195 |
Let's try dividing by 4:
1,301,195 ÷ 4 = 325,298.75
If the quotient is a whole number, then 4 and 325,298.75 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 | 1,301,195 | |
| -1 | 1,301,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 49 | 113 | 235 | 245 | 329 | 565 | 791 | 1,645 | 2,303 | 3,955 | 5,311 | 5,537 | 11,515 | 26,555 | 27,685 | 37,177 | 185,885 | 260,239 | 1,301,195 |
| -1 | -5 | -7 | -35 | -47 | -49 | -113 | -235 | -245 | -329 | -565 | -791 | -1,645 | -2,303 | -3,955 | -5,311 | -5,537 | -11,515 | -26,555 | -27,685 | -37,177 | -185,885 | -260,239 | -1,301,195 |
