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 51,747,371, 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 | 51,747,371 | |
| -1 | -51,747,371 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,747,371.
Example:
1 x 51,747,371 = 51,747,371
and
-1 x -51,747,371 = 51,747,371
Notice both answers equal 51,747,371
With that explanation out of the way, let's continue. Next, we take the number 51,747,371 and divide it by 2:
51,747,371 ÷ 2 = 25,873,685.5
If the quotient is a whole number, then 2 and 25,873,685.5 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 | 51,747,371 | |
| -1 | -51,747,371 |
Now, we try dividing 51,747,371 by 3:
51,747,371 ÷ 3 = 17,249,123.6667
If the quotient is a whole number, then 3 and 17,249,123.6667 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 | 51,747,371 | |
| -1 | -51,747,371 |
Let's try dividing by 4:
51,747,371 ÷ 4 = 12,936,842.75
If the quotient is a whole number, then 4 and 12,936,842.75 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 | 51,747,371 | |
| -1 | 51,747,371 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 41 | 221 | 533 | 697 | 5,711 | 9,061 | 74,243 | 97,087 | 234,151 | 1,262,131 | 3,043,963 | 3,980,567 | 51,747,371 |
| -1 | -13 | -17 | -41 | -221 | -533 | -697 | -5,711 | -9,061 | -74,243 | -97,087 | -234,151 | -1,262,131 | -3,043,963 | -3,980,567 | -51,747,371 |
