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 37,710,145, 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 | 37,710,145 | |
| -1 | -37,710,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,710,145.
Example:
1 x 37,710,145 = 37,710,145
and
-1 x -37,710,145 = 37,710,145
Notice both answers equal 37,710,145
With that explanation out of the way, let's continue. Next, we take the number 37,710,145 and divide it by 2:
37,710,145 ÷ 2 = 18,855,072.5
If the quotient is a whole number, then 2 and 18,855,072.5 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 | 37,710,145 | |
| -1 | -37,710,145 |
Now, we try dividing 37,710,145 by 3:
37,710,145 ÷ 3 = 12,570,048.3333
If the quotient is a whole number, then 3 and 12,570,048.3333 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 | 37,710,145 | |
| -1 | -37,710,145 |
Let's try dividing by 4:
37,710,145 ÷ 4 = 9,427,536.25
If the quotient is a whole number, then 4 and 9,427,536.25 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 | 37,710,145 | |
| -1 | 37,710,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 59 | 295 | 649 | 3,245 | 11,621 | 58,105 | 127,831 | 639,155 | 685,639 | 3,428,195 | 7,542,029 | 37,710,145 |
| -1 | -5 | -11 | -55 | -59 | -295 | -649 | -3,245 | -11,621 | -58,105 | -127,831 | -639,155 | -685,639 | -3,428,195 | -7,542,029 | -37,710,145 |
