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 2,361,947, 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 | 2,361,947 | |
| -1 | -2,361,947 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,361,947.
Example:
1 x 2,361,947 = 2,361,947
and
-1 x -2,361,947 = 2,361,947
Notice both answers equal 2,361,947
With that explanation out of the way, let's continue. Next, we take the number 2,361,947 and divide it by 2:
2,361,947 ÷ 2 = 1,180,973.5
If the quotient is a whole number, then 2 and 1,180,973.5 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 | 2,361,947 | |
| -1 | -2,361,947 |
Now, we try dividing 2,361,947 by 3:
2,361,947 ÷ 3 = 787,315.6667
If the quotient is a whole number, then 3 and 787,315.6667 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 | 2,361,947 | |
| -1 | -2,361,947 |
Let's try dividing by 4:
2,361,947 ÷ 4 = 590,486.75
If the quotient is a whole number, then 4 and 590,486.75 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 | 2,361,947 | |
| -1 | 2,361,947 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 43 | 49 | 59 | 133 | 301 | 413 | 817 | 931 | 1,121 | 2,107 | 2,537 | 2,891 | 5,719 | 7,847 | 17,759 | 40,033 | 48,203 | 54,929 | 124,313 | 337,421 | 2,361,947 |
| -1 | -7 | -19 | -43 | -49 | -59 | -133 | -301 | -413 | -817 | -931 | -1,121 | -2,107 | -2,537 | -2,891 | -5,719 | -7,847 | -17,759 | -40,033 | -48,203 | -54,929 | -124,313 | -337,421 | -2,361,947 |
