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 140,235,305, 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 | 140,235,305 | |
| -1 | -140,235,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,235,305.
Example:
1 x 140,235,305 = 140,235,305
and
-1 x -140,235,305 = 140,235,305
Notice both answers equal 140,235,305
With that explanation out of the way, let's continue. Next, we take the number 140,235,305 and divide it by 2:
140,235,305 ÷ 2 = 70,117,652.5
If the quotient is a whole number, then 2 and 70,117,652.5 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 | 140,235,305 | |
| -1 | -140,235,305 |
Now, we try dividing 140,235,305 by 3:
140,235,305 ÷ 3 = 46,745,101.6667
If the quotient is a whole number, then 3 and 46,745,101.6667 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 | 140,235,305 | |
| -1 | -140,235,305 |
Let's try dividing by 4:
140,235,305 ÷ 4 = 35,058,826.25
If the quotient is a whole number, then 4 and 35,058,826.25 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 | 140,235,305 | |
| -1 | 140,235,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 127 | 245 | 635 | 889 | 4,445 | 4,507 | 6,223 | 22,535 | 31,115 | 31,549 | 157,745 | 220,843 | 572,389 | 1,104,215 | 2,861,945 | 4,006,723 | 20,033,615 | 28,047,061 | 140,235,305 |
| -1 | -5 | -7 | -35 | -49 | -127 | -245 | -635 | -889 | -4,445 | -4,507 | -6,223 | -22,535 | -31,115 | -31,549 | -157,745 | -220,843 | -572,389 | -1,104,215 | -2,861,945 | -4,006,723 | -20,033,615 | -28,047,061 | -140,235,305 |
