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 3,694,789, 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 | 3,694,789 | |
| -1 | -3,694,789 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,694,789.
Example:
1 x 3,694,789 = 3,694,789
and
-1 x -3,694,789 = 3,694,789
Notice both answers equal 3,694,789
With that explanation out of the way, let's continue. Next, we take the number 3,694,789 and divide it by 2:
3,694,789 ÷ 2 = 1,847,394.5
If the quotient is a whole number, then 2 and 1,847,394.5 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 | 3,694,789 | |
| -1 | -3,694,789 |
Now, we try dividing 3,694,789 by 3:
3,694,789 ÷ 3 = 1,231,596.3333
If the quotient is a whole number, then 3 and 1,231,596.3333 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 | 3,694,789 | |
| -1 | -3,694,789 |
Let's try dividing by 4:
3,694,789 ÷ 4 = 923,697.25
If the quotient is a whole number, then 4 and 923,697.25 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 | 3,694,789 | |
| -1 | 3,694,789 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 53 | 161 | 371 | 433 | 1,219 | 3,031 | 8,533 | 9,959 | 22,949 | 69,713 | 160,643 | 527,827 | 3,694,789 |
| -1 | -7 | -23 | -53 | -161 | -371 | -433 | -1,219 | -3,031 | -8,533 | -9,959 | -22,949 | -69,713 | -160,643 | -527,827 | -3,694,789 |
