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 53,212,621, 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 | 53,212,621 | |
| -1 | -53,212,621 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,212,621.
Example:
1 x 53,212,621 = 53,212,621
and
-1 x -53,212,621 = 53,212,621
Notice both answers equal 53,212,621
With that explanation out of the way, let's continue. Next, we take the number 53,212,621 and divide it by 2:
53,212,621 ÷ 2 = 26,606,310.5
If the quotient is a whole number, then 2 and 26,606,310.5 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 | 53,212,621 | |
| -1 | -53,212,621 |
Now, we try dividing 53,212,621 by 3:
53,212,621 ÷ 3 = 17,737,540.3333
If the quotient is a whole number, then 3 and 17,737,540.3333 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 | 53,212,621 | |
| -1 | -53,212,621 |
Let's try dividing by 4:
53,212,621 ÷ 4 = 13,303,155.25
If the quotient is a whole number, then 4 and 13,303,155.25 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 | 53,212,621 | |
| -1 | 53,212,621 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 257 | 1,799 | 2,689 | 2,827 | 18,823 | 19,789 | 29,579 | 207,053 | 691,073 | 4,837,511 | 7,601,803 | 53,212,621 |
| -1 | -7 | -11 | -77 | -257 | -1,799 | -2,689 | -2,827 | -18,823 | -19,789 | -29,579 | -207,053 | -691,073 | -4,837,511 | -7,601,803 | -53,212,621 |
