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 254,480,701, 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 | 254,480,701 | |
| -1 | -254,480,701 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 254,480,701.
Example:
1 x 254,480,701 = 254,480,701
and
-1 x -254,480,701 = 254,480,701
Notice both answers equal 254,480,701
With that explanation out of the way, let's continue. Next, we take the number 254,480,701 and divide it by 2:
254,480,701 ÷ 2 = 127,240,350.5
If the quotient is a whole number, then 2 and 127,240,350.5 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 | 254,480,701 | |
| -1 | -254,480,701 |
Now, we try dividing 254,480,701 by 3:
254,480,701 ÷ 3 = 84,826,900.3333
If the quotient is a whole number, then 3 and 84,826,900.3333 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 | 254,480,701 | |
| -1 | -254,480,701 |
Let's try dividing by 4:
254,480,701 ÷ 4 = 63,620,175.25
If the quotient is a whole number, then 4 and 63,620,175.25 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 | 254,480,701 | |
| -1 | 254,480,701 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 73 | 799 | 1,241 | 3,431 | 4,363 | 58,327 | 74,171 | 205,061 | 318,499 | 3,486,037 | 5,414,483 | 14,969,453 | 254,480,701 |
| -1 | -17 | -47 | -73 | -799 | -1,241 | -3,431 | -4,363 | -58,327 | -74,171 | -205,061 | -318,499 | -3,486,037 | -5,414,483 | -14,969,453 | -254,480,701 |
