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 2,741,305, 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 | 2,741,305 | |
| -1 | -2,741,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,741,305.
Example:
1 x 2,741,305 = 2,741,305
and
-1 x -2,741,305 = 2,741,305
Notice both answers equal 2,741,305
With that explanation out of the way, let's continue. Next, we take the number 2,741,305 and divide it by 2:
2,741,305 ÷ 2 = 1,370,652.5
If the quotient is a whole number, then 2 and 1,370,652.5 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 | 2,741,305 | |
| -1 | -2,741,305 |
Now, we try dividing 2,741,305 by 3:
2,741,305 ÷ 3 = 913,768.3333
If the quotient is a whole number, then 3 and 913,768.3333 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 | 2,741,305 | |
| -1 | -2,741,305 |
Let's try dividing by 4:
2,741,305 ÷ 4 = 685,326.25
If the quotient is a whole number, then 4 and 685,326.25 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 | 2,741,305 | |
| -1 | 2,741,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 67 | 167 | 245 | 335 | 469 | 835 | 1,169 | 2,345 | 3,283 | 5,845 | 8,183 | 11,189 | 16,415 | 40,915 | 55,945 | 78,323 | 391,615 | 548,261 | 2,741,305 |
| -1 | -5 | -7 | -35 | -49 | -67 | -167 | -245 | -335 | -469 | -835 | -1,169 | -2,345 | -3,283 | -5,845 | -8,183 | -11,189 | -16,415 | -40,915 | -55,945 | -78,323 | -391,615 | -548,261 | -2,741,305 |
