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 3,073,651, 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 | 3,073,651 | |
| -1 | -3,073,651 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,073,651.
Example:
1 x 3,073,651 = 3,073,651
and
-1 x -3,073,651 = 3,073,651
Notice both answers equal 3,073,651
With that explanation out of the way, let's continue. Next, we take the number 3,073,651 and divide it by 2:
3,073,651 ÷ 2 = 1,536,825.5
If the quotient is a whole number, then 2 and 1,536,825.5 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 | 3,073,651 | |
| -1 | -3,073,651 |
Now, we try dividing 3,073,651 by 3:
3,073,651 ÷ 3 = 1,024,550.3333
If the quotient is a whole number, then 3 and 1,024,550.3333 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 | 3,073,651 | |
| -1 | -3,073,651 |
Let's try dividing by 4:
3,073,651 ÷ 4 = 768,412.75
If the quotient is a whole number, then 4 and 768,412.75 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 | 3,073,651 | |
| -1 | 3,073,651 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 23 | 119 | 161 | 391 | 1,123 | 2,737 | 7,861 | 19,091 | 25,829 | 133,637 | 180,803 | 439,093 | 3,073,651 |
| -1 | -7 | -17 | -23 | -119 | -161 | -391 | -1,123 | -2,737 | -7,861 | -19,091 | -25,829 | -133,637 | -180,803 | -439,093 | -3,073,651 |
