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 51,156,151, 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 | 51,156,151 | |
| -1 | -51,156,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,156,151.
Example:
1 x 51,156,151 = 51,156,151
and
-1 x -51,156,151 = 51,156,151
Notice both answers equal 51,156,151
With that explanation out of the way, let's continue. Next, we take the number 51,156,151 and divide it by 2:
51,156,151 ÷ 2 = 25,578,075.5
If the quotient is a whole number, then 2 and 25,578,075.5 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 | 51,156,151 | |
| -1 | -51,156,151 |
Now, we try dividing 51,156,151 by 3:
51,156,151 ÷ 3 = 17,052,050.3333
If the quotient is a whole number, then 3 and 17,052,050.3333 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 | 51,156,151 | |
| -1 | -51,156,151 |
Let's try dividing by 4:
51,156,151 ÷ 4 = 12,789,037.75
If the quotient is a whole number, then 4 and 12,789,037.75 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 | 51,156,151 | |
| -1 | 51,156,151 |
If you did it right, you will end up with this table:
| 1 | 19 | 41 | 97 | 677 | 779 | 1,843 | 3,977 | 12,863 | 27,757 | 65,669 | 75,563 | 527,383 | 1,247,711 | 2,692,429 | 51,156,151 |
| -1 | -19 | -41 | -97 | -677 | -779 | -1,843 | -3,977 | -12,863 | -27,757 | -65,669 | -75,563 | -527,383 | -1,247,711 | -2,692,429 | -51,156,151 |
