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 50,201,525, 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 | 50,201,525 | |
| -1 | -50,201,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,201,525.
Example:
1 x 50,201,525 = 50,201,525
and
-1 x -50,201,525 = 50,201,525
Notice both answers equal 50,201,525
With that explanation out of the way, let's continue. Next, we take the number 50,201,525 and divide it by 2:
50,201,525 ÷ 2 = 25,100,762.5
If the quotient is a whole number, then 2 and 25,100,762.5 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 | 50,201,525 | |
| -1 | -50,201,525 |
Now, we try dividing 50,201,525 by 3:
50,201,525 ÷ 3 = 16,733,841.6667
If the quotient is a whole number, then 3 and 16,733,841.6667 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 | 50,201,525 | |
| -1 | -50,201,525 |
Let's try dividing by 4:
50,201,525 ÷ 4 = 12,550,381.25
If the quotient is a whole number, then 4 and 12,550,381.25 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 | 50,201,525 | |
| -1 | 50,201,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 25 | 55 | 115 | 253 | 275 | 575 | 1,265 | 6,325 | 7,937 | 39,685 | 87,307 | 182,551 | 198,425 | 436,535 | 912,755 | 2,008,061 | 2,182,675 | 4,563,775 | 10,040,305 | 50,201,525 |
| -1 | -5 | -11 | -23 | -25 | -55 | -115 | -253 | -275 | -575 | -1,265 | -6,325 | -7,937 | -39,685 | -87,307 | -182,551 | -198,425 | -436,535 | -912,755 | -2,008,061 | -2,182,675 | -4,563,775 | -10,040,305 | -50,201,525 |
