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 254,200,177, 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 | 254,200,177 | |
| -1 | -254,200,177 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 254,200,177.
Example:
1 x 254,200,177 = 254,200,177
and
-1 x -254,200,177 = 254,200,177
Notice both answers equal 254,200,177
With that explanation out of the way, let's continue. Next, we take the number 254,200,177 and divide it by 2:
254,200,177 ÷ 2 = 127,100,088.5
If the quotient is a whole number, then 2 and 127,100,088.5 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 | 254,200,177 | |
| -1 | -254,200,177 |
Now, we try dividing 254,200,177 by 3:
254,200,177 ÷ 3 = 84,733,392.3333
If the quotient is a whole number, then 3 and 84,733,392.3333 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 | 254,200,177 | |
| -1 | -254,200,177 |
Let's try dividing by 4:
254,200,177 ÷ 4 = 63,550,044.25
If the quotient is a whole number, then 4 and 63,550,044.25 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 | 254,200,177 | |
| -1 | 254,200,177 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 419 | 2,933 | 4,609 | 7,879 | 32,263 | 55,153 | 86,669 | 606,683 | 3,301,301 | 23,109,107 | 36,314,311 | 254,200,177 |
| -1 | -7 | -11 | -77 | -419 | -2,933 | -4,609 | -7,879 | -32,263 | -55,153 | -86,669 | -606,683 | -3,301,301 | -23,109,107 | -36,314,311 | -254,200,177 |
