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 53,531,113, 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 | 53,531,113 | |
| -1 | -53,531,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,531,113.
Example:
1 x 53,531,113 = 53,531,113
and
-1 x -53,531,113 = 53,531,113
Notice both answers equal 53,531,113
With that explanation out of the way, let's continue. Next, we take the number 53,531,113 and divide it by 2:
53,531,113 ÷ 2 = 26,765,556.5
If the quotient is a whole number, then 2 and 26,765,556.5 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 | 53,531,113 | |
| -1 | -53,531,113 |
Now, we try dividing 53,531,113 by 3:
53,531,113 ÷ 3 = 17,843,704.3333
If the quotient is a whole number, then 3 and 17,843,704.3333 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 | 53,531,113 | |
| -1 | -53,531,113 |
Let's try dividing by 4:
53,531,113 ÷ 4 = 13,382,778.25
If the quotient is a whole number, then 4 and 13,382,778.25 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 | 53,531,113 | |
| -1 | 53,531,113 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 53 | 59 | 323 | 901 | 1,003 | 1,007 | 1,121 | 2,809 | 3,127 | 17,119 | 19,057 | 47,753 | 53,159 | 53,371 | 59,413 | 165,731 | 907,307 | 1,010,021 | 2,817,427 | 3,148,889 | 53,531,113 |
| -1 | -17 | -19 | -53 | -59 | -323 | -901 | -1,003 | -1,007 | -1,121 | -2,809 | -3,127 | -17,119 | -19,057 | -47,753 | -53,159 | -53,371 | -59,413 | -165,731 | -907,307 | -1,010,021 | -2,817,427 | -3,148,889 | -53,531,113 |
