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 51,101,071, 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 | 51,101,071 | |
| -1 | -51,101,071 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,101,071.
Example:
1 x 51,101,071 = 51,101,071
and
-1 x -51,101,071 = 51,101,071
Notice both answers equal 51,101,071
With that explanation out of the way, let's continue. Next, we take the number 51,101,071 and divide it by 2:
51,101,071 ÷ 2 = 25,550,535.5
If the quotient is a whole number, then 2 and 25,550,535.5 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 | 51,101,071 | |
| -1 | -51,101,071 |
Now, we try dividing 51,101,071 by 3:
51,101,071 ÷ 3 = 17,033,690.3333
If the quotient is a whole number, then 3 and 17,033,690.3333 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 | 51,101,071 | |
| -1 | -51,101,071 |
Let's try dividing by 4:
51,101,071 ÷ 4 = 12,775,267.75
If the quotient is a whole number, then 4 and 12,775,267.75 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 | 51,101,071 | |
| -1 | 51,101,071 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 49 | 79 | 301 | 307 | 553 | 2,107 | 2,149 | 3,397 | 3,871 | 13,201 | 15,043 | 23,779 | 24,253 | 92,407 | 166,453 | 169,771 | 646,849 | 1,042,879 | 1,188,397 | 7,300,153 | 51,101,071 |
| -1 | -7 | -43 | -49 | -79 | -301 | -307 | -553 | -2,107 | -2,149 | -3,397 | -3,871 | -13,201 | -15,043 | -23,779 | -24,253 | -92,407 | -166,453 | -169,771 | -646,849 | -1,042,879 | -1,188,397 | -7,300,153 | -51,101,071 |
