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 36,151,745, 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 | 36,151,745 | |
| -1 | -36,151,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 36,151,745.
Example:
1 x 36,151,745 = 36,151,745
and
-1 x -36,151,745 = 36,151,745
Notice both answers equal 36,151,745
With that explanation out of the way, let's continue. Next, we take the number 36,151,745 and divide it by 2:
36,151,745 ÷ 2 = 18,075,872.5
If the quotient is a whole number, then 2 and 18,075,872.5 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 | 36,151,745 | |
| -1 | -36,151,745 |
Now, we try dividing 36,151,745 by 3:
36,151,745 ÷ 3 = 12,050,581.6667
If the quotient is a whole number, then 3 and 12,050,581.6667 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 | 36,151,745 | |
| -1 | -36,151,745 |
Let's try dividing by 4:
36,151,745 ÷ 4 = 9,037,936.25
If the quotient is a whole number, then 4 and 9,037,936.25 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 | 36,151,745 | |
| -1 | 36,151,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 44,909 | 224,545 | 314,363 | 1,032,907 | 1,571,815 | 5,164,535 | 7,230,349 | 36,151,745 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -44,909 | -224,545 | -314,363 | -1,032,907 | -1,571,815 | -5,164,535 | -7,230,349 | -36,151,745 |
