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 3,174,427, 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 | 3,174,427 | |
| -1 | -3,174,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,174,427.
Example:
1 x 3,174,427 = 3,174,427
and
-1 x -3,174,427 = 3,174,427
Notice both answers equal 3,174,427
With that explanation out of the way, let's continue. Next, we take the number 3,174,427 and divide it by 2:
3,174,427 ÷ 2 = 1,587,213.5
If the quotient is a whole number, then 2 and 1,587,213.5 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 | 3,174,427 | |
| -1 | -3,174,427 |
Now, we try dividing 3,174,427 by 3:
3,174,427 ÷ 3 = 1,058,142.3333
If the quotient is a whole number, then 3 and 1,058,142.3333 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 | 3,174,427 | |
| -1 | -3,174,427 |
Let's try dividing by 4:
3,174,427 ÷ 4 = 793,606.75
If the quotient is a whole number, then 4 and 793,606.75 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 | 3,174,427 | |
| -1 | 3,174,427 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 47 | 137 | 493 | 799 | 1,363 | 2,329 | 3,973 | 6,439 | 23,171 | 67,541 | 109,463 | 186,731 | 3,174,427 |
| -1 | -17 | -29 | -47 | -137 | -493 | -799 | -1,363 | -2,329 | -3,973 | -6,439 | -23,171 | -67,541 | -109,463 | -186,731 | -3,174,427 |
