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 53,210,477, 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 | 53,210,477 | |
| -1 | -53,210,477 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,210,477.
Example:
1 x 53,210,477 = 53,210,477
and
-1 x -53,210,477 = 53,210,477
Notice both answers equal 53,210,477
With that explanation out of the way, let's continue. Next, we take the number 53,210,477 and divide it by 2:
53,210,477 ÷ 2 = 26,605,238.5
If the quotient is a whole number, then 2 and 26,605,238.5 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 | 53,210,477 | |
| -1 | -53,210,477 |
Now, we try dividing 53,210,477 by 3:
53,210,477 ÷ 3 = 17,736,825.6667
If the quotient is a whole number, then 3 and 17,736,825.6667 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 | 53,210,477 | |
| -1 | -53,210,477 |
Let's try dividing by 4:
53,210,477 ÷ 4 = 13,302,619.25
If the quotient is a whole number, then 4 and 13,302,619.25 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 | 53,210,477 | |
| -1 | 53,210,477 |
If you did it right, you will end up with this table:
| 1 | 23 | 31 | 37 | 713 | 851 | 1,147 | 2,017 | 26,381 | 46,391 | 62,527 | 74,629 | 1,438,121 | 1,716,467 | 2,313,499 | 53,210,477 |
| -1 | -23 | -31 | -37 | -713 | -851 | -1,147 | -2,017 | -26,381 | -46,391 | -62,527 | -74,629 | -1,438,121 | -1,716,467 | -2,313,499 | -53,210,477 |
