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 49,291,435, 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 | 49,291,435 | |
| -1 | -49,291,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 49,291,435.
Example:
1 x 49,291,435 = 49,291,435
and
-1 x -49,291,435 = 49,291,435
Notice both answers equal 49,291,435
With that explanation out of the way, let's continue. Next, we take the number 49,291,435 and divide it by 2:
49,291,435 ÷ 2 = 24,645,717.5
If the quotient is a whole number, then 2 and 24,645,717.5 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 | 49,291,435 | |
| -1 | -49,291,435 |
Now, we try dividing 49,291,435 by 3:
49,291,435 ÷ 3 = 16,430,478.3333
If the quotient is a whole number, then 3 and 16,430,478.3333 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 | 49,291,435 | |
| -1 | -49,291,435 |
Let's try dividing by 4:
49,291,435 ÷ 4 = 12,322,858.75
If the quotient is a whole number, then 4 and 12,322,858.75 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 | 49,291,435 | |
| -1 | 49,291,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 109 | 149 | 545 | 607 | 745 | 3,035 | 16,241 | 66,163 | 81,205 | 90,443 | 330,815 | 452,215 | 9,858,287 | 49,291,435 |
| -1 | -5 | -109 | -149 | -545 | -607 | -745 | -3,035 | -16,241 | -66,163 | -81,205 | -90,443 | -330,815 | -452,215 | -9,858,287 | -49,291,435 |
