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 37,154,039, 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 | 37,154,039 | |
| -1 | -37,154,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,154,039.
Example:
1 x 37,154,039 = 37,154,039
and
-1 x -37,154,039 = 37,154,039
Notice both answers equal 37,154,039
With that explanation out of the way, let's continue. Next, we take the number 37,154,039 and divide it by 2:
37,154,039 ÷ 2 = 18,577,019.5
If the quotient is a whole number, then 2 and 18,577,019.5 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 | 37,154,039 | |
| -1 | -37,154,039 |
Now, we try dividing 37,154,039 by 3:
37,154,039 ÷ 3 = 12,384,679.6667
If the quotient is a whole number, then 3 and 12,384,679.6667 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 | 37,154,039 | |
| -1 | -37,154,039 |
Let's try dividing by 4:
37,154,039 ÷ 4 = 9,288,509.75
If the quotient is a whole number, then 4 and 9,288,509.75 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 | 37,154,039 | |
| -1 | 37,154,039 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 299 | 313 | 397 | 4,069 | 5,161 | 7,199 | 9,131 | 93,587 | 118,703 | 124,261 | 1,615,393 | 2,858,003 | 37,154,039 |
| -1 | -13 | -23 | -299 | -313 | -397 | -4,069 | -5,161 | -7,199 | -9,131 | -93,587 | -118,703 | -124,261 | -1,615,393 | -2,858,003 | -37,154,039 |
