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 40,700,803, 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 | 40,700,803 | |
| -1 | -40,700,803 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,700,803.
Example:
1 x 40,700,803 = 40,700,803
and
-1 x -40,700,803 = 40,700,803
Notice both answers equal 40,700,803
With that explanation out of the way, let's continue. Next, we take the number 40,700,803 and divide it by 2:
40,700,803 ÷ 2 = 20,350,401.5
If the quotient is a whole number, then 2 and 20,350,401.5 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 | 40,700,803 | |
| -1 | -40,700,803 |
Now, we try dividing 40,700,803 by 3:
40,700,803 ÷ 3 = 13,566,934.3333
If the quotient is a whole number, then 3 and 13,566,934.3333 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 | 40,700,803 | |
| -1 | -40,700,803 |
Let's try dividing by 4:
40,700,803 ÷ 4 = 10,175,200.75
If the quotient is a whole number, then 4 and 10,175,200.75 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 | 40,700,803 | |
| -1 | 40,700,803 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 241 | 1,181 | 2,651 | 3,133 | 12,991 | 15,353 | 34,463 | 168,883 | 284,621 | 3,130,831 | 3,700,073 | 40,700,803 |
| -1 | -11 | -13 | -143 | -241 | -1,181 | -2,651 | -3,133 | -12,991 | -15,353 | -34,463 | -168,883 | -284,621 | -3,130,831 | -3,700,073 | -40,700,803 |
