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 230,574,175, 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 | 230,574,175 | |
| -1 | -230,574,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,574,175.
Example:
1 x 230,574,175 = 230,574,175
and
-1 x -230,574,175 = 230,574,175
Notice both answers equal 230,574,175
With that explanation out of the way, let's continue. Next, we take the number 230,574,175 and divide it by 2:
230,574,175 ÷ 2 = 115,287,087.5
If the quotient is a whole number, then 2 and 115,287,087.5 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 | 230,574,175 | |
| -1 | -230,574,175 |
Now, we try dividing 230,574,175 by 3:
230,574,175 ÷ 3 = 76,858,058.3333
If the quotient is a whole number, then 3 and 76,858,058.3333 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 | 230,574,175 | |
| -1 | -230,574,175 |
Let's try dividing by 4:
230,574,175 ÷ 4 = 57,643,543.75
If the quotient is a whole number, then 4 and 57,643,543.75 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 | 230,574,175 | |
| -1 | 230,574,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 325 | 547 | 1,297 | 2,735 | 6,485 | 7,111 | 13,675 | 16,861 | 32,425 | 35,555 | 84,305 | 177,775 | 421,525 | 709,459 | 3,547,295 | 9,222,967 | 17,736,475 | 46,114,835 | 230,574,175 |
| -1 | -5 | -13 | -25 | -65 | -325 | -547 | -1,297 | -2,735 | -6,485 | -7,111 | -13,675 | -16,861 | -32,425 | -35,555 | -84,305 | -177,775 | -421,525 | -709,459 | -3,547,295 | -9,222,967 | -17,736,475 | -46,114,835 | -230,574,175 |
