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 2,955,245, 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 | 2,955,245 | |
| -1 | -2,955,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,955,245.
Example:
1 x 2,955,245 = 2,955,245
and
-1 x -2,955,245 = 2,955,245
Notice both answers equal 2,955,245
With that explanation out of the way, let's continue. Next, we take the number 2,955,245 and divide it by 2:
2,955,245 ÷ 2 = 1,477,622.5
If the quotient is a whole number, then 2 and 1,477,622.5 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 | 2,955,245 | |
| -1 | -2,955,245 |
Now, we try dividing 2,955,245 by 3:
2,955,245 ÷ 3 = 985,081.6667
If the quotient is a whole number, then 3 and 985,081.6667 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 | 2,955,245 | |
| -1 | -2,955,245 |
Let's try dividing by 4:
2,955,245 ÷ 4 = 738,811.25
If the quotient is a whole number, then 4 and 738,811.25 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 | 2,955,245 | |
| -1 | 2,955,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 89 | 145 | 229 | 445 | 1,145 | 2,581 | 6,641 | 12,905 | 20,381 | 33,205 | 101,905 | 591,049 | 2,955,245 |
| -1 | -5 | -29 | -89 | -145 | -229 | -445 | -1,145 | -2,581 | -6,641 | -12,905 | -20,381 | -33,205 | -101,905 | -591,049 | -2,955,245 |
