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 40,701,349, 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 | 40,701,349 | |
| -1 | -40,701,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,701,349.
Example:
1 x 40,701,349 = 40,701,349
and
-1 x -40,701,349 = 40,701,349
Notice both answers equal 40,701,349
With that explanation out of the way, let's continue. Next, we take the number 40,701,349 and divide it by 2:
40,701,349 ÷ 2 = 20,350,674.5
If the quotient is a whole number, then 2 and 20,350,674.5 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 | 40,701,349 | |
| -1 | -40,701,349 |
Now, we try dividing 40,701,349 by 3:
40,701,349 ÷ 3 = 13,567,116.3333
If the quotient is a whole number, then 3 and 13,567,116.3333 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 | 40,701,349 | |
| -1 | -40,701,349 |
Let's try dividing by 4:
40,701,349 ÷ 4 = 10,175,337.25
If the quotient is a whole number, then 4 and 10,175,337.25 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 | 40,701,349 | |
| -1 | 40,701,349 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 43 | 221 | 559 | 731 | 4,283 | 9,503 | 55,679 | 72,811 | 184,169 | 946,543 | 2,394,197 | 3,130,873 | 40,701,349 |
| -1 | -13 | -17 | -43 | -221 | -559 | -731 | -4,283 | -9,503 | -55,679 | -72,811 | -184,169 | -946,543 | -2,394,197 | -3,130,873 | -40,701,349 |
