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 51,321,283, 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 | 51,321,283 | |
| -1 | -51,321,283 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,321,283.
Example:
1 x 51,321,283 = 51,321,283
and
-1 x -51,321,283 = 51,321,283
Notice both answers equal 51,321,283
With that explanation out of the way, let's continue. Next, we take the number 51,321,283 and divide it by 2:
51,321,283 ÷ 2 = 25,660,641.5
If the quotient is a whole number, then 2 and 25,660,641.5 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 | 51,321,283 | |
| -1 | -51,321,283 |
Now, we try dividing 51,321,283 by 3:
51,321,283 ÷ 3 = 17,107,094.3333
If the quotient is a whole number, then 3 and 17,107,094.3333 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 | 51,321,283 | |
| -1 | -51,321,283 |
Let's try dividing by 4:
51,321,283 ÷ 4 = 12,830,320.75
If the quotient is a whole number, then 4 and 12,830,320.75 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 | 51,321,283 | |
| -1 | 51,321,283 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 181 | 221 | 1,283 | 2,353 | 3,077 | 16,679 | 21,811 | 40,001 | 232,223 | 283,543 | 3,018,899 | 3,947,791 | 51,321,283 |
| -1 | -13 | -17 | -181 | -221 | -1,283 | -2,353 | -3,077 | -16,679 | -21,811 | -40,001 | -232,223 | -283,543 | -3,018,899 | -3,947,791 | -51,321,283 |
