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 575,075,347, 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 | 575,075,347 | |
| -1 | -575,075,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 575,075,347.
Example:
1 x 575,075,347 = 575,075,347
and
-1 x -575,075,347 = 575,075,347
Notice both answers equal 575,075,347
With that explanation out of the way, let's continue. Next, we take the number 575,075,347 and divide it by 2:
575,075,347 ÷ 2 = 287,537,673.5
If the quotient is a whole number, then 2 and 287,537,673.5 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 | 575,075,347 | |
| -1 | -575,075,347 |
Now, we try dividing 575,075,347 by 3:
575,075,347 ÷ 3 = 191,691,782.3333
If the quotient is a whole number, then 3 and 191,691,782.3333 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 | 575,075,347 | |
| -1 | -575,075,347 |
Let's try dividing by 4:
575,075,347 ÷ 4 = 143,768,836.75
If the quotient is a whole number, then 4 and 143,768,836.75 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 | 575,075,347 | |
| -1 | 575,075,347 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 239 | 1,673 | 2,629 | 18,403 | 31,249 | 218,743 | 343,739 | 2,406,173 | 7,468,511 | 52,279,577 | 82,153,621 | 575,075,347 |
| -1 | -7 | -11 | -77 | -239 | -1,673 | -2,629 | -18,403 | -31,249 | -218,743 | -343,739 | -2,406,173 | -7,468,511 | -52,279,577 | -82,153,621 | -575,075,347 |
