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 3,074,617, 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 | 3,074,617 | |
| -1 | -3,074,617 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,074,617.
Example:
1 x 3,074,617 = 3,074,617
and
-1 x -3,074,617 = 3,074,617
Notice both answers equal 3,074,617
With that explanation out of the way, let's continue. Next, we take the number 3,074,617 and divide it by 2:
3,074,617 ÷ 2 = 1,537,308.5
If the quotient is a whole number, then 2 and 1,537,308.5 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 | 3,074,617 | |
| -1 | -3,074,617 |
Now, we try dividing 3,074,617 by 3:
3,074,617 ÷ 3 = 1,024,872.3333
If the quotient is a whole number, then 3 and 1,024,872.3333 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 | 3,074,617 | |
| -1 | -3,074,617 |
Let's try dividing by 4:
3,074,617 ÷ 4 = 768,654.25
If the quotient is a whole number, then 4 and 768,654.25 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 | 3,074,617 | |
| -1 | 3,074,617 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 23 | 91 | 113 | 161 | 169 | 299 | 791 | 1,183 | 1,469 | 2,093 | 2,599 | 3,887 | 10,283 | 18,193 | 19,097 | 27,209 | 33,787 | 133,679 | 236,509 | 439,231 | 3,074,617 |
| -1 | -7 | -13 | -23 | -91 | -113 | -161 | -169 | -299 | -791 | -1,183 | -1,469 | -2,093 | -2,599 | -3,887 | -10,283 | -18,193 | -19,097 | -27,209 | -33,787 | -133,679 | -236,509 | -439,231 | -3,074,617 |
