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 540,053,159, 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 | 540,053,159 | |
-1 | -540,053,159 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 540,053,159.
Example:
1 x 540,053,159 = 540,053,159
and
-1 x -540,053,159 = 540,053,159
Notice both answers equal 540,053,159
With that explanation out of the way, let's continue. Next, we take the number 540,053,159 and divide it by 2:
540,053,159 ÷ 2 = 270,026,579.5
If the quotient is a whole number, then 2 and 270,026,579.5 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 | 540,053,159 | |
-1 | -540,053,159 |
Now, we try dividing 540,053,159 by 3:
540,053,159 ÷ 3 = 180,017,719.6667
If the quotient is a whole number, then 3 and 180,017,719.6667 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 | 540,053,159 | |
-1 | -540,053,159 |
Let's try dividing by 4:
540,053,159 ÷ 4 = 135,013,289.75
If the quotient is a whole number, then 4 and 135,013,289.75 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 | 540,053,159 | |
-1 | 540,053,159 |
If you did it right, you will end up with this table:
1 | 449 | 1,202,791 | 540,053,159 |
-1 | -449 | -1,202,791 | -540,053,159 |
