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 3,194,113, 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 | 3,194,113 | |
| -1 | -3,194,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,194,113.
Example:
1 x 3,194,113 = 3,194,113
and
-1 x -3,194,113 = 3,194,113
Notice both answers equal 3,194,113
With that explanation out of the way, let's continue. Next, we take the number 3,194,113 and divide it by 2:
3,194,113 ÷ 2 = 1,597,056.5
If the quotient is a whole number, then 2 and 1,597,056.5 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 | 3,194,113 | |
| -1 | -3,194,113 |
Now, we try dividing 3,194,113 by 3:
3,194,113 ÷ 3 = 1,064,704.3333
If the quotient is a whole number, then 3 and 1,064,704.3333 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 | 3,194,113 | |
| -1 | -3,194,113 |
Let's try dividing by 4:
3,194,113 ÷ 4 = 798,528.25
If the quotient is a whole number, then 4 and 798,528.25 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 | 3,194,113 | |
| -1 | 3,194,113 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 97 | 149 | 221 | 1,261 | 1,649 | 1,937 | 2,533 | 14,453 | 21,437 | 32,929 | 187,889 | 245,701 | 3,194,113 |
| -1 | -13 | -17 | -97 | -149 | -221 | -1,261 | -1,649 | -1,937 | -2,533 | -14,453 | -21,437 | -32,929 | -187,889 | -245,701 | -3,194,113 |
