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 98,474,255, 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 | 98,474,255 | |
| -1 | -98,474,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 98,474,255.
Example:
1 x 98,474,255 = 98,474,255
and
-1 x -98,474,255 = 98,474,255
Notice both answers equal 98,474,255
With that explanation out of the way, let's continue. Next, we take the number 98,474,255 and divide it by 2:
98,474,255 ÷ 2 = 49,237,127.5
If the quotient is a whole number, then 2 and 49,237,127.5 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 | 98,474,255 | |
| -1 | -98,474,255 |
Now, we try dividing 98,474,255 by 3:
98,474,255 ÷ 3 = 32,824,751.6667
If the quotient is a whole number, then 3 and 32,824,751.6667 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 | 98,474,255 | |
| -1 | -98,474,255 |
Let's try dividing by 4:
98,474,255 ÷ 4 = 24,618,563.75
If the quotient is a whole number, then 4 and 24,618,563.75 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 | 98,474,255 | |
| -1 | 98,474,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 67 | 335 | 737 | 3,685 | 26,723 | 133,615 | 293,953 | 1,469,765 | 1,790,441 | 8,952,205 | 19,694,851 | 98,474,255 |
| -1 | -5 | -11 | -55 | -67 | -335 | -737 | -3,685 | -26,723 | -133,615 | -293,953 | -1,469,765 | -1,790,441 | -8,952,205 | -19,694,851 | -98,474,255 |
