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 51,152,233, 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 | 51,152,233 | |
| -1 | -51,152,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,152,233.
Example:
1 x 51,152,233 = 51,152,233
and
-1 x -51,152,233 = 51,152,233
Notice both answers equal 51,152,233
With that explanation out of the way, let's continue. Next, we take the number 51,152,233 and divide it by 2:
51,152,233 ÷ 2 = 25,576,116.5
If the quotient is a whole number, then 2 and 25,576,116.5 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 | 51,152,233 | |
| -1 | -51,152,233 |
Now, we try dividing 51,152,233 by 3:
51,152,233 ÷ 3 = 17,050,744.3333
If the quotient is a whole number, then 3 and 17,050,744.3333 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 | 51,152,233 | |
| -1 | -51,152,233 |
Let's try dividing by 4:
51,152,233 ÷ 4 = 12,788,058.25
If the quotient is a whole number, then 4 and 12,788,058.25 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 | 51,152,233 | |
| -1 | 51,152,233 |
If you did it right, you will end up with this table:
| 1 | 11 | 59 | 269 | 293 | 649 | 2,959 | 3,223 | 15,871 | 17,287 | 78,817 | 174,581 | 190,157 | 866,987 | 4,650,203 | 51,152,233 |
| -1 | -11 | -59 | -269 | -293 | -649 | -2,959 | -3,223 | -15,871 | -17,287 | -78,817 | -174,581 | -190,157 | -866,987 | -4,650,203 | -51,152,233 |
