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 51,531,053, 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 | 51,531,053 | |
| -1 | -51,531,053 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,531,053.
Example:
1 x 51,531,053 = 51,531,053
and
-1 x -51,531,053 = 51,531,053
Notice both answers equal 51,531,053
With that explanation out of the way, let's continue. Next, we take the number 51,531,053 and divide it by 2:
51,531,053 ÷ 2 = 25,765,526.5
If the quotient is a whole number, then 2 and 25,765,526.5 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 | 51,531,053 | |
| -1 | -51,531,053 |
Now, we try dividing 51,531,053 by 3:
51,531,053 ÷ 3 = 17,177,017.6667
If the quotient is a whole number, then 3 and 17,177,017.6667 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 | 51,531,053 | |
| -1 | -51,531,053 |
Let's try dividing by 4:
51,531,053 ÷ 4 = 12,882,763.25
If the quotient is a whole number, then 4 and 12,882,763.25 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 | 51,531,053 | |
| -1 | 51,531,053 |
If you did it right, you will end up with this table:
| 1 | 7 | 139 | 211 | 251 | 973 | 1,477 | 1,757 | 29,329 | 34,889 | 52,961 | 205,303 | 244,223 | 370,727 | 7,361,579 | 51,531,053 |
| -1 | -7 | -139 | -211 | -251 | -973 | -1,477 | -1,757 | -29,329 | -34,889 | -52,961 | -205,303 | -244,223 | -370,727 | -7,361,579 | -51,531,053 |
