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 240,824,615, 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 | 240,824,615 | |
| -1 | -240,824,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,824,615.
Example:
1 x 240,824,615 = 240,824,615
and
-1 x -240,824,615 = 240,824,615
Notice both answers equal 240,824,615
With that explanation out of the way, let's continue. Next, we take the number 240,824,615 and divide it by 2:
240,824,615 ÷ 2 = 120,412,307.5
If the quotient is a whole number, then 2 and 120,412,307.5 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 | 240,824,615 | |
| -1 | -240,824,615 |
Now, we try dividing 240,824,615 by 3:
240,824,615 ÷ 3 = 80,274,871.6667
If the quotient is a whole number, then 3 and 80,274,871.6667 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 | 240,824,615 | |
| -1 | -240,824,615 |
Let's try dividing by 4:
240,824,615 ÷ 4 = 60,206,153.75
If the quotient is a whole number, then 4 and 60,206,153.75 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 | 240,824,615 | |
| -1 | 240,824,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 151 | 307 | 755 | 1,039 | 1,535 | 5,195 | 46,357 | 156,889 | 231,785 | 318,973 | 784,445 | 1,594,865 | 48,164,923 | 240,824,615 |
| -1 | -5 | -151 | -307 | -755 | -1,039 | -1,535 | -5,195 | -46,357 | -156,889 | -231,785 | -318,973 | -784,445 | -1,594,865 | -48,164,923 | -240,824,615 |
