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 140,224,399, 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 | 140,224,399 | |
| -1 | -140,224,399 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,224,399.
Example:
1 x 140,224,399 = 140,224,399
and
-1 x -140,224,399 = 140,224,399
Notice both answers equal 140,224,399
With that explanation out of the way, let's continue. Next, we take the number 140,224,399 and divide it by 2:
140,224,399 ÷ 2 = 70,112,199.5
If the quotient is a whole number, then 2 and 70,112,199.5 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 | 140,224,399 | |
| -1 | -140,224,399 |
Now, we try dividing 140,224,399 by 3:
140,224,399 ÷ 3 = 46,741,466.3333
If the quotient is a whole number, then 3 and 46,741,466.3333 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 | 140,224,399 | |
| -1 | -140,224,399 |
Let's try dividing by 4:
140,224,399 ÷ 4 = 35,056,099.75
If the quotient is a whole number, then 4 and 35,056,099.75 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 | 140,224,399 | |
| -1 | 140,224,399 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 307 | 2,149 | 2,837 | 7,061 | 19,859 | 49,427 | 65,251 | 456,757 | 870,959 | 6,096,713 | 20,032,057 | 140,224,399 |
| -1 | -7 | -23 | -161 | -307 | -2,149 | -2,837 | -7,061 | -19,859 | -49,427 | -65,251 | -456,757 | -870,959 | -6,096,713 | -20,032,057 | -140,224,399 |
