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 98,634,055, 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 | 98,634,055 | |
| -1 | -98,634,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 98,634,055.
Example:
1 x 98,634,055 = 98,634,055
and
-1 x -98,634,055 = 98,634,055
Notice both answers equal 98,634,055
With that explanation out of the way, let's continue. Next, we take the number 98,634,055 and divide it by 2:
98,634,055 ÷ 2 = 49,317,027.5
If the quotient is a whole number, then 2 and 49,317,027.5 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 | 98,634,055 | |
| -1 | -98,634,055 |
Now, we try dividing 98,634,055 by 3:
98,634,055 ÷ 3 = 32,878,018.3333
If the quotient is a whole number, then 3 and 32,878,018.3333 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 | 98,634,055 | |
| -1 | -98,634,055 |
Let's try dividing by 4:
98,634,055 ÷ 4 = 24,658,513.75
If the quotient is a whole number, then 4 and 24,658,513.75 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 | 98,634,055 | |
| -1 | 98,634,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 293 | 1,465 | 3,809 | 5,179 | 19,045 | 25,895 | 67,327 | 336,635 | 1,517,447 | 7,587,235 | 19,726,811 | 98,634,055 |
| -1 | -5 | -13 | -65 | -293 | -1,465 | -3,809 | -5,179 | -19,045 | -25,895 | -67,327 | -336,635 | -1,517,447 | -7,587,235 | -19,726,811 | -98,634,055 |
