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 2,946,995, 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 | 2,946,995 | |
| -1 | -2,946,995 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,946,995.
Example:
1 x 2,946,995 = 2,946,995
and
-1 x -2,946,995 = 2,946,995
Notice both answers equal 2,946,995
With that explanation out of the way, let's continue. Next, we take the number 2,946,995 and divide it by 2:
2,946,995 ÷ 2 = 1,473,497.5
If the quotient is a whole number, then 2 and 1,473,497.5 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 | 2,946,995 | |
| -1 | -2,946,995 |
Now, we try dividing 2,946,995 by 3:
2,946,995 ÷ 3 = 982,331.6667
If the quotient is a whole number, then 3 and 982,331.6667 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 | 2,946,995 | |
| -1 | -2,946,995 |
Let's try dividing by 4:
2,946,995 ÷ 4 = 736,748.75
If the quotient is a whole number, then 4 and 736,748.75 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 | 2,946,995 | |
| -1 | 2,946,995 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 67 | 95 | 335 | 463 | 1,273 | 2,315 | 6,365 | 8,797 | 31,021 | 43,985 | 155,105 | 589,399 | 2,946,995 |
| -1 | -5 | -19 | -67 | -95 | -335 | -463 | -1,273 | -2,315 | -6,365 | -8,797 | -31,021 | -43,985 | -155,105 | -589,399 | -2,946,995 |
