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 51,400,349, 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 | 51,400,349 | |
| -1 | -51,400,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,400,349.
Example:
1 x 51,400,349 = 51,400,349
and
-1 x -51,400,349 = 51,400,349
Notice both answers equal 51,400,349
With that explanation out of the way, let's continue. Next, we take the number 51,400,349 and divide it by 2:
51,400,349 ÷ 2 = 25,700,174.5
If the quotient is a whole number, then 2 and 25,700,174.5 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 | 51,400,349 | |
| -1 | -51,400,349 |
Now, we try dividing 51,400,349 by 3:
51,400,349 ÷ 3 = 17,133,449.6667
If the quotient is a whole number, then 3 and 17,133,449.6667 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 | 51,400,349 | |
| -1 | -51,400,349 |
Let's try dividing by 4:
51,400,349 ÷ 4 = 12,850,087.25
If the quotient is a whole number, then 4 and 12,850,087.25 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 | 51,400,349 | |
| -1 | 51,400,349 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 51,349 | 359,443 | 564,839 | 667,537 | 3,953,873 | 4,672,759 | 7,342,907 | 51,400,349 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -51,349 | -359,443 | -564,839 | -667,537 | -3,953,873 | -4,672,759 | -7,342,907 | -51,400,349 |
