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 9,785,117, 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 | 9,785,117 | |
-1 | -9,785,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,785,117.
Example:
1 x 9,785,117 = 9,785,117
and
-1 x -9,785,117 = 9,785,117
Notice both answers equal 9,785,117
With that explanation out of the way, let's continue. Next, we take the number 9,785,117 and divide it by 2:
9,785,117 ÷ 2 = 4,892,558.5
If the quotient is a whole number, then 2 and 4,892,558.5 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 | 9,785,117 | |
-1 | -9,785,117 |
Now, we try dividing 9,785,117 by 3:
9,785,117 ÷ 3 = 3,261,705.6667
If the quotient is a whole number, then 3 and 3,261,705.6667 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 | 9,785,117 | |
-1 | -9,785,117 |
Let's try dividing by 4:
9,785,117 ÷ 4 = 2,446,279.25
If the quotient is a whole number, then 4 and 2,446,279.25 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 | 9,785,117 | |
-1 | 9,785,117 |
If you did it right, you will end up with this table:
1 | 2,371 | 4,127 | 9,785,117 |
-1 | -2,371 | -4,127 | -9,785,117 |
