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 254,150,635, 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 | 254,150,635 | |
| -1 | -254,150,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 254,150,635.
Example:
1 x 254,150,635 = 254,150,635
and
-1 x -254,150,635 = 254,150,635
Notice both answers equal 254,150,635
With that explanation out of the way, let's continue. Next, we take the number 254,150,635 and divide it by 2:
254,150,635 ÷ 2 = 127,075,317.5
If the quotient is a whole number, then 2 and 127,075,317.5 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 | 254,150,635 | |
| -1 | -254,150,635 |
Now, we try dividing 254,150,635 by 3:
254,150,635 ÷ 3 = 84,716,878.3333
If the quotient is a whole number, then 3 and 84,716,878.3333 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 | 254,150,635 | |
| -1 | -254,150,635 |
Let's try dividing by 4:
254,150,635 ÷ 4 = 63,537,658.75
If the quotient is a whole number, then 4 and 63,537,658.75 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 | 254,150,635 | |
| -1 | 254,150,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 53 | 145 | 265 | 1,537 | 7,685 | 33,071 | 165,355 | 959,059 | 1,752,763 | 4,795,295 | 8,763,815 | 50,830,127 | 254,150,635 |
| -1 | -5 | -29 | -53 | -145 | -265 | -1,537 | -7,685 | -33,071 | -165,355 | -959,059 | -1,752,763 | -4,795,295 | -8,763,815 | -50,830,127 | -254,150,635 |
