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 583,727,221, 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 | 583,727,221 | |
| -1 | -583,727,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 583,727,221.
Example:
1 x 583,727,221 = 583,727,221
and
-1 x -583,727,221 = 583,727,221
Notice both answers equal 583,727,221
With that explanation out of the way, let's continue. Next, we take the number 583,727,221 and divide it by 2:
583,727,221 ÷ 2 = 291,863,610.5
If the quotient is a whole number, then 2 and 291,863,610.5 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 | 583,727,221 | |
| -1 | -583,727,221 |
Now, we try dividing 583,727,221 by 3:
583,727,221 ÷ 3 = 194,575,740.3333
If the quotient is a whole number, then 3 and 194,575,740.3333 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 | 583,727,221 | |
| -1 | -583,727,221 |
Let's try dividing by 4:
583,727,221 ÷ 4 = 145,931,805.25
If the quotient is a whole number, then 4 and 145,931,805.25 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 | 583,727,221 | |
| -1 | 583,727,221 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 547 | 3,829 | 6,017 | 13,859 | 42,119 | 97,013 | 152,449 | 1,067,143 | 7,580,873 | 53,066,111 | 83,389,603 | 583,727,221 |
| -1 | -7 | -11 | -77 | -547 | -3,829 | -6,017 | -13,859 | -42,119 | -97,013 | -152,449 | -1,067,143 | -7,580,873 | -53,066,111 | -83,389,603 | -583,727,221 |
