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 3,857,729, 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 | 3,857,729 | |
-1 | -3,857,729 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,857,729.
Example:
1 x 3,857,729 = 3,857,729
and
-1 x -3,857,729 = 3,857,729
Notice both answers equal 3,857,729
With that explanation out of the way, let's continue. Next, we take the number 3,857,729 and divide it by 2:
3,857,729 ÷ 2 = 1,928,864.5
If the quotient is a whole number, then 2 and 1,928,864.5 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 | 3,857,729 | |
-1 | -3,857,729 |
Now, we try dividing 3,857,729 by 3:
3,857,729 ÷ 3 = 1,285,909.6667
If the quotient is a whole number, then 3 and 1,285,909.6667 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 | 3,857,729 | |
-1 | -3,857,729 |
Let's try dividing by 4:
3,857,729 ÷ 4 = 964,432.25
If the quotient is a whole number, then 4 and 964,432.25 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 | 3,857,729 | |
-1 | 3,857,729 |
If you did it right, you will end up with this table:
1 | 269 | 14,341 | 3,857,729 |
-1 | -269 | -14,341 | -3,857,729 |
