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 50,290,513, 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 | 50,290,513 | |
| -1 | -50,290,513 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,290,513.
Example:
1 x 50,290,513 = 50,290,513
and
-1 x -50,290,513 = 50,290,513
Notice both answers equal 50,290,513
With that explanation out of the way, let's continue. Next, we take the number 50,290,513 and divide it by 2:
50,290,513 ÷ 2 = 25,145,256.5
If the quotient is a whole number, then 2 and 25,145,256.5 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 | 50,290,513 | |
| -1 | -50,290,513 |
Now, we try dividing 50,290,513 by 3:
50,290,513 ÷ 3 = 16,763,504.3333
If the quotient is a whole number, then 3 and 16,763,504.3333 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 | 50,290,513 | |
| -1 | -50,290,513 |
Let's try dividing by 4:
50,290,513 ÷ 4 = 12,572,628.25
If the quotient is a whole number, then 4 and 12,572,628.25 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 | 50,290,513 | |
| -1 | 50,290,513 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 169 | 637 | 1,183 | 6,073 | 8,281 | 42,511 | 78,949 | 297,577 | 552,643 | 1,026,337 | 3,868,501 | 7,184,359 | 50,290,513 |
| -1 | -7 | -13 | -49 | -91 | -169 | -637 | -1,183 | -6,073 | -8,281 | -42,511 | -78,949 | -297,577 | -552,643 | -1,026,337 | -3,868,501 | -7,184,359 | -50,290,513 |
