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 74,783, 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 | 74,783 | |
-1 | -74,783 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 74,783.
Example:
1 x 74,783 = 74,783
and
-1 x -74,783 = 74,783
Notice both answers equal 74,783
With that explanation out of the way, let's continue. Next, we take the number 74,783 and divide it by 2:
74,783 ÷ 2 = 37,391.5
If the quotient is a whole number, then 2 and 37,391.5 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 | 74,783 | |
-1 | -74,783 |
Now, we try dividing 74,783 by 3:
74,783 ÷ 3 = 24,927.6667
If the quotient is a whole number, then 3 and 24,927.6667 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 | 74,783 | |
-1 | -74,783 |
Let's try dividing by 4:
74,783 ÷ 4 = 18,695.75
If the quotient is a whole number, then 4 and 18,695.75 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 | 74,783 | |
-1 | 74,783 |
If you did it right, you will end up with this table:
1 | 17 | 53 | 83 | 901 | 1,411 | 4,399 | 74,783 |
-1 | -17 | -53 | -83 | -901 | -1,411 | -4,399 | -74,783 |
