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 51,305,527, 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 | 51,305,527 | |
| -1 | -51,305,527 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,305,527.
Example:
1 x 51,305,527 = 51,305,527
and
-1 x -51,305,527 = 51,305,527
Notice both answers equal 51,305,527
With that explanation out of the way, let's continue. Next, we take the number 51,305,527 and divide it by 2:
51,305,527 ÷ 2 = 25,652,763.5
If the quotient is a whole number, then 2 and 25,652,763.5 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 | 51,305,527 | |
| -1 | -51,305,527 |
Now, we try dividing 51,305,527 by 3:
51,305,527 ÷ 3 = 17,101,842.3333
If the quotient is a whole number, then 3 and 17,101,842.3333 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 | 51,305,527 | |
| -1 | -51,305,527 |
Let's try dividing by 4:
51,305,527 ÷ 4 = 12,826,381.75
If the quotient is a whole number, then 4 and 12,826,381.75 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 | 51,305,527 | |
| -1 | 51,305,527 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 31 | 91 | 169 | 217 | 403 | 1,183 | 1,399 | 2,821 | 5,239 | 9,793 | 18,187 | 36,673 | 43,369 | 127,309 | 236,431 | 303,583 | 563,797 | 1,655,017 | 3,946,579 | 7,329,361 | 51,305,527 |
| -1 | -7 | -13 | -31 | -91 | -169 | -217 | -403 | -1,183 | -1,399 | -2,821 | -5,239 | -9,793 | -18,187 | -36,673 | -43,369 | -127,309 | -236,431 | -303,583 | -563,797 | -1,655,017 | -3,946,579 | -7,329,361 | -51,305,527 |
