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 40,036,535, 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 | 40,036,535 | |
| -1 | -40,036,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,036,535.
Example:
1 x 40,036,535 = 40,036,535
and
-1 x -40,036,535 = 40,036,535
Notice both answers equal 40,036,535
With that explanation out of the way, let's continue. Next, we take the number 40,036,535 and divide it by 2:
40,036,535 ÷ 2 = 20,018,267.5
If the quotient is a whole number, then 2 and 20,018,267.5 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 | 40,036,535 | |
| -1 | -40,036,535 |
Now, we try dividing 40,036,535 by 3:
40,036,535 ÷ 3 = 13,345,511.6667
If the quotient is a whole number, then 3 and 13,345,511.6667 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 | 40,036,535 | |
| -1 | -40,036,535 |
Let's try dividing by 4:
40,036,535 ÷ 4 = 10,009,133.75
If the quotient is a whole number, then 4 and 10,009,133.75 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 | 40,036,535 | |
| -1 | 40,036,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 103,991 | 519,955 | 727,937 | 1,143,901 | 3,639,685 | 5,719,505 | 8,007,307 | 40,036,535 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -103,991 | -519,955 | -727,937 | -1,143,901 | -3,639,685 | -5,719,505 | -8,007,307 | -40,036,535 |
