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 51,462,671, 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 | 51,462,671 | |
| -1 | -51,462,671 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,462,671.
Example:
1 x 51,462,671 = 51,462,671
and
-1 x -51,462,671 = 51,462,671
Notice both answers equal 51,462,671
With that explanation out of the way, let's continue. Next, we take the number 51,462,671 and divide it by 2:
51,462,671 ÷ 2 = 25,731,335.5
If the quotient is a whole number, then 2 and 25,731,335.5 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 | 51,462,671 | |
| -1 | -51,462,671 |
Now, we try dividing 51,462,671 by 3:
51,462,671 ÷ 3 = 17,154,223.6667
If the quotient is a whole number, then 3 and 17,154,223.6667 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 | 51,462,671 | |
| -1 | -51,462,671 |
Let's try dividing by 4:
51,462,671 ÷ 4 = 12,865,667.75
If the quotient is a whole number, then 4 and 12,865,667.75 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 | 51,462,671 | |
| -1 | 51,462,671 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 97 | 481 | 1,103 | 1,261 | 3,589 | 14,339 | 40,811 | 46,657 | 106,991 | 530,543 | 1,390,883 | 3,958,667 | 51,462,671 |
| -1 | -13 | -37 | -97 | -481 | -1,103 | -1,261 | -3,589 | -14,339 | -40,811 | -46,657 | -106,991 | -530,543 | -1,390,883 | -3,958,667 | -51,462,671 |
