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 50,053,531, 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 | 50,053,531 | |
| -1 | -50,053,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,053,531.
Example:
1 x 50,053,531 = 50,053,531
and
-1 x -50,053,531 = 50,053,531
Notice both answers equal 50,053,531
With that explanation out of the way, let's continue. Next, we take the number 50,053,531 and divide it by 2:
50,053,531 ÷ 2 = 25,026,765.5
If the quotient is a whole number, then 2 and 25,026,765.5 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 | 50,053,531 | |
| -1 | -50,053,531 |
Now, we try dividing 50,053,531 by 3:
50,053,531 ÷ 3 = 16,684,510.3333
If the quotient is a whole number, then 3 and 16,684,510.3333 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 | 50,053,531 | |
| -1 | -50,053,531 |
Let's try dividing by 4:
50,053,531 ÷ 4 = 12,513,382.75
If the quotient is a whole number, then 4 and 12,513,382.75 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 | 50,053,531 | |
| -1 | 50,053,531 |
If you did it right, you will end up with this table:
| 1 | 11 | 79 | 239 | 241 | 869 | 2,629 | 2,651 | 18,881 | 19,039 | 57,599 | 207,691 | 209,429 | 633,589 | 4,550,321 | 50,053,531 |
| -1 | -11 | -79 | -239 | -241 | -869 | -2,629 | -2,651 | -18,881 | -19,039 | -57,599 | -207,691 | -209,429 | -633,589 | -4,550,321 | -50,053,531 |
