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 140,214,305, 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 | 140,214,305 | |
| -1 | -140,214,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,214,305.
Example:
1 x 140,214,305 = 140,214,305
and
-1 x -140,214,305 = 140,214,305
Notice both answers equal 140,214,305
With that explanation out of the way, let's continue. Next, we take the number 140,214,305 and divide it by 2:
140,214,305 ÷ 2 = 70,107,152.5
If the quotient is a whole number, then 2 and 70,107,152.5 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 | 140,214,305 | |
| -1 | -140,214,305 |
Now, we try dividing 140,214,305 by 3:
140,214,305 ÷ 3 = 46,738,101.6667
If the quotient is a whole number, then 3 and 46,738,101.6667 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 | 140,214,305 | |
| -1 | -140,214,305 |
Let's try dividing by 4:
140,214,305 ÷ 4 = 35,053,576.25
If the quotient is a whole number, then 4 and 35,053,576.25 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 | 140,214,305 | |
| -1 | 140,214,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 364,193 | 1,820,965 | 2,549,351 | 4,006,123 | 12,746,755 | 20,030,615 | 28,042,861 | 140,214,305 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -364,193 | -1,820,965 | -2,549,351 | -4,006,123 | -12,746,755 | -20,030,615 | -28,042,861 | -140,214,305 |
