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 1,346,891, 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 | 1,346,891 | |
| -1 | -1,346,891 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,346,891.
Example:
1 x 1,346,891 = 1,346,891
and
-1 x -1,346,891 = 1,346,891
Notice both answers equal 1,346,891
With that explanation out of the way, let's continue. Next, we take the number 1,346,891 and divide it by 2:
1,346,891 ÷ 2 = 673,445.5
If the quotient is a whole number, then 2 and 673,445.5 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 | 1,346,891 | |
| -1 | -1,346,891 |
Now, we try dividing 1,346,891 by 3:
1,346,891 ÷ 3 = 448,963.6667
If the quotient is a whole number, then 3 and 448,963.6667 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 | 1,346,891 | |
| -1 | -1,346,891 |
Let's try dividing by 4:
1,346,891 ÷ 4 = 336,722.75
If the quotient is a whole number, then 4 and 336,722.75 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 | 1,346,891 | |
| -1 | 1,346,891 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 19 | 41 | 91 | 133 | 247 | 287 | 361 | 533 | 779 | 1,729 | 2,527 | 3,731 | 4,693 | 5,453 | 10,127 | 14,801 | 32,851 | 70,889 | 103,607 | 192,413 | 1,346,891 |
| -1 | -7 | -13 | -19 | -41 | -91 | -133 | -247 | -287 | -361 | -533 | -779 | -1,729 | -2,527 | -3,731 | -4,693 | -5,453 | -10,127 | -14,801 | -32,851 | -70,889 | -103,607 | -192,413 | -1,346,891 |
