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 140,322,425, 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 | 140,322,425 | |
| -1 | -140,322,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,322,425.
Example:
1 x 140,322,425 = 140,322,425
and
-1 x -140,322,425 = 140,322,425
Notice both answers equal 140,322,425
With that explanation out of the way, let's continue. Next, we take the number 140,322,425 and divide it by 2:
140,322,425 ÷ 2 = 70,161,212.5
If the quotient is a whole number, then 2 and 70,161,212.5 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 | 140,322,425 | |
| -1 | -140,322,425 |
Now, we try dividing 140,322,425 by 3:
140,322,425 ÷ 3 = 46,774,141.6667
If the quotient is a whole number, then 3 and 46,774,141.6667 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 | 140,322,425 | |
| -1 | -140,322,425 |
Let's try dividing by 4:
140,322,425 ÷ 4 = 35,080,606.25
If the quotient is a whole number, then 4 and 35,080,606.25 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 | 140,322,425 | |
| -1 | 140,322,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 73 | 115 | 365 | 575 | 1,679 | 1,825 | 3,343 | 8,395 | 16,715 | 41,975 | 76,889 | 83,575 | 244,039 | 384,445 | 1,220,195 | 1,922,225 | 5,612,897 | 6,100,975 | 28,064,485 | 140,322,425 |
| -1 | -5 | -23 | -25 | -73 | -115 | -365 | -575 | -1,679 | -1,825 | -3,343 | -8,395 | -16,715 | -41,975 | -76,889 | -83,575 | -244,039 | -384,445 | -1,220,195 | -1,922,225 | -5,612,897 | -6,100,975 | -28,064,485 | -140,322,425 |
