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 57,143,819, 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 | 57,143,819 | |
-1 | -57,143,819 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,143,819.
Example:
1 x 57,143,819 = 57,143,819
and
-1 x -57,143,819 = 57,143,819
Notice both answers equal 57,143,819
With that explanation out of the way, let's continue. Next, we take the number 57,143,819 and divide it by 2:
57,143,819 ÷ 2 = 28,571,909.5
If the quotient is a whole number, then 2 and 28,571,909.5 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 | 57,143,819 | |
-1 | -57,143,819 |
Now, we try dividing 57,143,819 by 3:
57,143,819 ÷ 3 = 19,047,939.6667
If the quotient is a whole number, then 3 and 19,047,939.6667 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 | 57,143,819 | |
-1 | -57,143,819 |
Let's try dividing by 4:
57,143,819 ÷ 4 = 14,285,954.75
If the quotient is a whole number, then 4 and 14,285,954.75 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 | 57,143,819 | |
-1 | 57,143,819 |
If you did it right, you will end up with this table:
1 | 31 | 1,843,349 | 57,143,819 |
-1 | -31 | -1,843,349 | -57,143,819 |
