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 37,442,251, 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 | 37,442,251 | |
| -1 | -37,442,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,442,251.
Example:
1 x 37,442,251 = 37,442,251
and
-1 x -37,442,251 = 37,442,251
Notice both answers equal 37,442,251
With that explanation out of the way, let's continue. Next, we take the number 37,442,251 and divide it by 2:
37,442,251 ÷ 2 = 18,721,125.5
If the quotient is a whole number, then 2 and 18,721,125.5 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 | 37,442,251 | |
| -1 | -37,442,251 |
Now, we try dividing 37,442,251 by 3:
37,442,251 ÷ 3 = 12,480,750.3333
If the quotient is a whole number, then 3 and 12,480,750.3333 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 | 37,442,251 | |
| -1 | -37,442,251 |
Let's try dividing by 4:
37,442,251 ÷ 4 = 9,360,562.75
If the quotient is a whole number, then 4 and 9,360,562.75 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 | 37,442,251 | |
| -1 | 37,442,251 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 103 | 721 | 1,133 | 4,721 | 7,931 | 33,047 | 51,931 | 363,517 | 486,263 | 3,403,841 | 5,348,893 | 37,442,251 |
| -1 | -7 | -11 | -77 | -103 | -721 | -1,133 | -4,721 | -7,931 | -33,047 | -51,931 | -363,517 | -486,263 | -3,403,841 | -5,348,893 | -37,442,251 |
