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 140,003,401, 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 | 140,003,401 | |
| -1 | -140,003,401 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,003,401.
Example:
1 x 140,003,401 = 140,003,401
and
-1 x -140,003,401 = 140,003,401
Notice both answers equal 140,003,401
With that explanation out of the way, let's continue. Next, we take the number 140,003,401 and divide it by 2:
140,003,401 ÷ 2 = 70,001,700.5
If the quotient is a whole number, then 2 and 70,001,700.5 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 | 140,003,401 | |
| -1 | -140,003,401 |
Now, we try dividing 140,003,401 by 3:
140,003,401 ÷ 3 = 46,667,800.3333
If the quotient is a whole number, then 3 and 46,667,800.3333 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 | 140,003,401 | |
| -1 | -140,003,401 |
Let's try dividing by 4:
140,003,401 ÷ 4 = 35,000,850.25
If the quotient is a whole number, then 4 and 35,000,850.25 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 | 140,003,401 | |
| -1 | 140,003,401 |
If you did it right, you will end up with this table:
| 1 | 59 | 67 | 107 | 331 | 3,953 | 6,313 | 7,169 | 19,529 | 22,177 | 35,417 | 422,971 | 1,308,443 | 2,089,603 | 2,372,939 | 140,003,401 |
| -1 | -59 | -67 | -107 | -331 | -3,953 | -6,313 | -7,169 | -19,529 | -22,177 | -35,417 | -422,971 | -1,308,443 | -2,089,603 | -2,372,939 | -140,003,401 |
