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 588,601,615, 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 | 588,601,615 | |
| -1 | -588,601,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 588,601,615.
Example:
1 x 588,601,615 = 588,601,615
and
-1 x -588,601,615 = 588,601,615
Notice both answers equal 588,601,615
With that explanation out of the way, let's continue. Next, we take the number 588,601,615 and divide it by 2:
588,601,615 ÷ 2 = 294,300,807.5
If the quotient is a whole number, then 2 and 294,300,807.5 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 | 588,601,615 | |
| -1 | -588,601,615 |
Now, we try dividing 588,601,615 by 3:
588,601,615 ÷ 3 = 196,200,538.3333
If the quotient is a whole number, then 3 and 196,200,538.3333 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 | 588,601,615 | |
| -1 | -588,601,615 |
Let's try dividing by 4:
588,601,615 ÷ 4 = 147,150,403.75
If the quotient is a whole number, then 4 and 147,150,403.75 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 | 588,601,615 | |
| -1 | 588,601,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 431 | 2,155 | 3,017 | 15,085 | 39,019 | 195,095 | 273,133 | 1,365,665 | 16,817,189 | 84,085,945 | 117,720,323 | 588,601,615 |
| -1 | -5 | -7 | -35 | -431 | -2,155 | -3,017 | -15,085 | -39,019 | -195,095 | -273,133 | -1,365,665 | -16,817,189 | -84,085,945 | -117,720,323 | -588,601,615 |
