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 3,142,447, 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 | 3,142,447 | |
| -1 | -3,142,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,142,447.
Example:
1 x 3,142,447 = 3,142,447
and
-1 x -3,142,447 = 3,142,447
Notice both answers equal 3,142,447
With that explanation out of the way, let's continue. Next, we take the number 3,142,447 and divide it by 2:
3,142,447 ÷ 2 = 1,571,223.5
If the quotient is a whole number, then 2 and 1,571,223.5 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 | 3,142,447 | |
| -1 | -3,142,447 |
Now, we try dividing 3,142,447 by 3:
3,142,447 ÷ 3 = 1,047,482.3333
If the quotient is a whole number, then 3 and 1,047,482.3333 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 | 3,142,447 | |
| -1 | -3,142,447 |
Let's try dividing by 4:
3,142,447 ÷ 4 = 785,611.75
If the quotient is a whole number, then 4 and 785,611.75 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 | 3,142,447 | |
| -1 | 3,142,447 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 37 | 77 | 259 | 407 | 1,103 | 2,849 | 7,721 | 12,133 | 40,811 | 84,931 | 285,677 | 448,921 | 3,142,447 |
| -1 | -7 | -11 | -37 | -77 | -259 | -407 | -1,103 | -2,849 | -7,721 | -12,133 | -40,811 | -84,931 | -285,677 | -448,921 | -3,142,447 |
