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 1,941,407, 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 | 1,941,407 | |
| -1 | -1,941,407 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,941,407.
Example:
1 x 1,941,407 = 1,941,407
and
-1 x -1,941,407 = 1,941,407
Notice both answers equal 1,941,407
With that explanation out of the way, let's continue. Next, we take the number 1,941,407 and divide it by 2:
1,941,407 ÷ 2 = 970,703.5
If the quotient is a whole number, then 2 and 970,703.5 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 | 1,941,407 | |
| -1 | -1,941,407 |
Now, we try dividing 1,941,407 by 3:
1,941,407 ÷ 3 = 647,135.6667
If the quotient is a whole number, then 3 and 647,135.6667 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 | 1,941,407 | |
| -1 | -1,941,407 |
Let's try dividing by 4:
1,941,407 ÷ 4 = 485,351.75
If the quotient is a whole number, then 4 and 485,351.75 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 | 1,941,407 | |
| -1 | 1,941,407 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 43 | 151 | 299 | 559 | 989 | 1,963 | 3,473 | 6,493 | 12,857 | 45,149 | 84,409 | 149,339 | 1,941,407 |
| -1 | -13 | -23 | -43 | -151 | -299 | -559 | -989 | -1,963 | -3,473 | -6,493 | -12,857 | -45,149 | -84,409 | -149,339 | -1,941,407 |
