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 572,407,235, 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 | 572,407,235 | |
| -1 | -572,407,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 572,407,235.
Example:
1 x 572,407,235 = 572,407,235
and
-1 x -572,407,235 = 572,407,235
Notice both answers equal 572,407,235
With that explanation out of the way, let's continue. Next, we take the number 572,407,235 and divide it by 2:
572,407,235 ÷ 2 = 286,203,617.5
If the quotient is a whole number, then 2 and 286,203,617.5 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 | 572,407,235 | |
| -1 | -572,407,235 |
Now, we try dividing 572,407,235 by 3:
572,407,235 ÷ 3 = 190,802,411.6667
If the quotient is a whole number, then 3 and 190,802,411.6667 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 | 572,407,235 | |
| -1 | -572,407,235 |
Let's try dividing by 4:
572,407,235 ÷ 4 = 143,101,808.75
If the quotient is a whole number, then 4 and 143,101,808.75 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 | 572,407,235 | |
| -1 | 572,407,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 137 | 365 | 685 | 10,001 | 11,447 | 50,005 | 57,235 | 835,631 | 1,568,239 | 4,178,155 | 7,841,195 | 114,481,447 | 572,407,235 |
| -1 | -5 | -73 | -137 | -365 | -685 | -10,001 | -11,447 | -50,005 | -57,235 | -835,631 | -1,568,239 | -4,178,155 | -7,841,195 | -114,481,447 | -572,407,235 |
