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 50,420,455, 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 | 50,420,455 | |
| -1 | -50,420,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,420,455.
Example:
1 x 50,420,455 = 50,420,455
and
-1 x -50,420,455 = 50,420,455
Notice both answers equal 50,420,455
With that explanation out of the way, let's continue. Next, we take the number 50,420,455 and divide it by 2:
50,420,455 ÷ 2 = 25,210,227.5
If the quotient is a whole number, then 2 and 25,210,227.5 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 | 50,420,455 | |
| -1 | -50,420,455 |
Now, we try dividing 50,420,455 by 3:
50,420,455 ÷ 3 = 16,806,818.3333
If the quotient is a whole number, then 3 and 16,806,818.3333 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 | 50,420,455 | |
| -1 | -50,420,455 |
Let's try dividing by 4:
50,420,455 ÷ 4 = 12,605,113.75
If the quotient is a whole number, then 4 and 12,605,113.75 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 | 50,420,455 | |
| -1 | 50,420,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 449 | 607 | 2,245 | 3,035 | 16,613 | 22,459 | 83,065 | 112,295 | 272,543 | 1,362,715 | 10,084,091 | 50,420,455 |
| -1 | -5 | -37 | -185 | -449 | -607 | -2,245 | -3,035 | -16,613 | -22,459 | -83,065 | -112,295 | -272,543 | -1,362,715 | -10,084,091 | -50,420,455 |
