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 52,238,671, 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 | 52,238,671 | |
| -1 | -52,238,671 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,238,671.
Example:
1 x 52,238,671 = 52,238,671
and
-1 x -52,238,671 = 52,238,671
Notice both answers equal 52,238,671
With that explanation out of the way, let's continue. Next, we take the number 52,238,671 and divide it by 2:
52,238,671 ÷ 2 = 26,119,335.5
If the quotient is a whole number, then 2 and 26,119,335.5 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 | 52,238,671 | |
| -1 | -52,238,671 |
Now, we try dividing 52,238,671 by 3:
52,238,671 ÷ 3 = 17,412,890.3333
If the quotient is a whole number, then 3 and 17,412,890.3333 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 | 52,238,671 | |
| -1 | -52,238,671 |
Let's try dividing by 4:
52,238,671 ÷ 4 = 13,059,667.75
If the quotient is a whole number, then 4 and 13,059,667.75 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 | 52,238,671 | |
| -1 | 52,238,671 |
If you did it right, you will end up with this table:
| 1 | 17 | 79 | 97 | 401 | 1,343 | 1,649 | 6,817 | 7,663 | 31,679 | 38,897 | 130,271 | 538,543 | 661,249 | 3,072,863 | 52,238,671 |
| -1 | -17 | -79 | -97 | -401 | -1,343 | -1,649 | -6,817 | -7,663 | -31,679 | -38,897 | -130,271 | -538,543 | -661,249 | -3,072,863 | -52,238,671 |
