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 37,312,555, 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 | 37,312,555 | |
| -1 | -37,312,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,312,555.
Example:
1 x 37,312,555 = 37,312,555
and
-1 x -37,312,555 = 37,312,555
Notice both answers equal 37,312,555
With that explanation out of the way, let's continue. Next, we take the number 37,312,555 and divide it by 2:
37,312,555 ÷ 2 = 18,656,277.5
If the quotient is a whole number, then 2 and 18,656,277.5 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 | 37,312,555 | |
| -1 | -37,312,555 |
Now, we try dividing 37,312,555 by 3:
37,312,555 ÷ 3 = 12,437,518.3333
If the quotient is a whole number, then 3 and 12,437,518.3333 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 | 37,312,555 | |
| -1 | -37,312,555 |
Let's try dividing by 4:
37,312,555 ÷ 4 = 9,328,138.75
If the quotient is a whole number, then 4 and 9,328,138.75 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 | 37,312,555 | |
| -1 | 37,312,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 46,351 | 231,755 | 324,457 | 1,066,073 | 1,622,285 | 5,330,365 | 7,462,511 | 37,312,555 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -46,351 | -231,755 | -324,457 | -1,066,073 | -1,622,285 | -5,330,365 | -7,462,511 | -37,312,555 |
