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 53,220,121, 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 | 53,220,121 | |
| -1 | -53,220,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,220,121.
Example:
1 x 53,220,121 = 53,220,121
and
-1 x -53,220,121 = 53,220,121
Notice both answers equal 53,220,121
With that explanation out of the way, let's continue. Next, we take the number 53,220,121 and divide it by 2:
53,220,121 ÷ 2 = 26,610,060.5
If the quotient is a whole number, then 2 and 26,610,060.5 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 | 53,220,121 | |
| -1 | -53,220,121 |
Now, we try dividing 53,220,121 by 3:
53,220,121 ÷ 3 = 17,740,040.3333
If the quotient is a whole number, then 3 and 17,740,040.3333 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 | 53,220,121 | |
| -1 | -53,220,121 |
Let's try dividing by 4:
53,220,121 ÷ 4 = 13,305,030.25
If the quotient is a whole number, then 4 and 13,305,030.25 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 | 53,220,121 | |
| -1 | 53,220,121 |
If you did it right, you will end up with this table:
| 1 | 19 | 47 | 61 | 893 | 977 | 1,159 | 2,867 | 18,563 | 45,919 | 54,473 | 59,597 | 872,461 | 1,132,343 | 2,801,059 | 53,220,121 |
| -1 | -19 | -47 | -61 | -893 | -977 | -1,159 | -2,867 | -18,563 | -45,919 | -54,473 | -59,597 | -872,461 | -1,132,343 | -2,801,059 | -53,220,121 |
