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 1,010,191, 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 | 1,010,191 | |
| -1 | -1,010,191 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,010,191.
Example:
1 x 1,010,191 = 1,010,191
and
-1 x -1,010,191 = 1,010,191
Notice both answers equal 1,010,191
With that explanation out of the way, let's continue. Next, we take the number 1,010,191 and divide it by 2:
1,010,191 ÷ 2 = 505,095.5
If the quotient is a whole number, then 2 and 505,095.5 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 | 1,010,191 | |
| -1 | -1,010,191 |
Now, we try dividing 1,010,191 by 3:
1,010,191 ÷ 3 = 336,730.3333
If the quotient is a whole number, then 3 and 336,730.3333 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 | 1,010,191 | |
| -1 | -1,010,191 |
Let's try dividing by 4:
1,010,191 ÷ 4 = 252,547.75
If the quotient is a whole number, then 4 and 252,547.75 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 | 1,010,191 | |
| -1 | 1,010,191 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 91 | 119 | 221 | 653 | 1,547 | 4,571 | 8,489 | 11,101 | 59,423 | 77,707 | 144,313 | 1,010,191 |
| -1 | -7 | -13 | -17 | -91 | -119 | -221 | -653 | -1,547 | -4,571 | -8,489 | -11,101 | -59,423 | -77,707 | -144,313 | -1,010,191 |
