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 572,407,075, 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 | 572,407,075 | |
| -1 | -572,407,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 572,407,075.
Example:
1 x 572,407,075 = 572,407,075
and
-1 x -572,407,075 = 572,407,075
Notice both answers equal 572,407,075
With that explanation out of the way, let's continue. Next, we take the number 572,407,075 and divide it by 2:
572,407,075 ÷ 2 = 286,203,537.5
If the quotient is a whole number, then 2 and 286,203,537.5 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 | 572,407,075 | |
| -1 | -572,407,075 |
Now, we try dividing 572,407,075 by 3:
572,407,075 ÷ 3 = 190,802,358.3333
If the quotient is a whole number, then 3 and 190,802,358.3333 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 | 572,407,075 | |
| -1 | -572,407,075 |
Let's try dividing by 4:
572,407,075 ÷ 4 = 143,101,768.75
If the quotient is a whole number, then 4 and 143,101,768.75 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 | 572,407,075 | |
| -1 | 572,407,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 145 | 725 | 789,527 | 3,947,635 | 19,738,175 | 22,896,283 | 114,481,415 | 572,407,075 |
| -1 | -5 | -25 | -29 | -145 | -725 | -789,527 | -3,947,635 | -19,738,175 | -22,896,283 | -114,481,415 | -572,407,075 |
