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 2,942,975, 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 | 2,942,975 | |
| -1 | -2,942,975 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,942,975.
Example:
1 x 2,942,975 = 2,942,975
and
-1 x -2,942,975 = 2,942,975
Notice both answers equal 2,942,975
With that explanation out of the way, let's continue. Next, we take the number 2,942,975 and divide it by 2:
2,942,975 ÷ 2 = 1,471,487.5
If the quotient is a whole number, then 2 and 1,471,487.5 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 | 2,942,975 | |
| -1 | -2,942,975 |
Now, we try dividing 2,942,975 by 3:
2,942,975 ÷ 3 = 980,991.6667
If the quotient is a whole number, then 3 and 980,991.6667 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 | 2,942,975 | |
| -1 | -2,942,975 |
Let's try dividing by 4:
2,942,975 ÷ 4 = 735,743.75
If the quotient is a whole number, then 4 and 735,743.75 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 | 2,942,975 | |
| -1 | 2,942,975 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 67 | 175 | 251 | 335 | 469 | 1,255 | 1,675 | 1,757 | 2,345 | 6,275 | 8,785 | 11,725 | 16,817 | 43,925 | 84,085 | 117,719 | 420,425 | 588,595 | 2,942,975 |
| -1 | -5 | -7 | -25 | -35 | -67 | -175 | -251 | -335 | -469 | -1,255 | -1,675 | -1,757 | -2,345 | -6,275 | -8,785 | -11,725 | -16,817 | -43,925 | -84,085 | -117,719 | -420,425 | -588,595 | -2,942,975 |
