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 40,302,353, 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 | 40,302,353 | |
| -1 | -40,302,353 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,302,353.
Example:
1 x 40,302,353 = 40,302,353
and
-1 x -40,302,353 = 40,302,353
Notice both answers equal 40,302,353
With that explanation out of the way, let's continue. Next, we take the number 40,302,353 and divide it by 2:
40,302,353 ÷ 2 = 20,151,176.5
If the quotient is a whole number, then 2 and 20,151,176.5 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 | 40,302,353 | |
| -1 | -40,302,353 |
Now, we try dividing 40,302,353 by 3:
40,302,353 ÷ 3 = 13,434,117.6667
If the quotient is a whole number, then 3 and 13,434,117.6667 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 | 40,302,353 | |
| -1 | -40,302,353 |
Let's try dividing by 4:
40,302,353 ÷ 4 = 10,075,588.25
If the quotient is a whole number, then 4 and 10,075,588.25 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 | 40,302,353 | |
| -1 | 40,302,353 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 151 | 419 | 637 | 1,057 | 1,963 | 2,933 | 5,447 | 7,399 | 13,741 | 20,531 | 38,129 | 63,269 | 96,187 | 266,903 | 442,883 | 822,497 | 3,100,181 | 5,757,479 | 40,302,353 |
| -1 | -7 | -13 | -49 | -91 | -151 | -419 | -637 | -1,057 | -1,963 | -2,933 | -5,447 | -7,399 | -13,741 | -20,531 | -38,129 | -63,269 | -96,187 | -266,903 | -442,883 | -822,497 | -3,100,181 | -5,757,479 | -40,302,353 |
