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 140,300,771, 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 | 140,300,771 | |
| -1 | -140,300,771 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,300,771.
Example:
1 x 140,300,771 = 140,300,771
and
-1 x -140,300,771 = 140,300,771
Notice both answers equal 140,300,771
With that explanation out of the way, let's continue. Next, we take the number 140,300,771 and divide it by 2:
140,300,771 ÷ 2 = 70,150,385.5
If the quotient is a whole number, then 2 and 70,150,385.5 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 | 140,300,771 | |
| -1 | -140,300,771 |
Now, we try dividing 140,300,771 by 3:
140,300,771 ÷ 3 = 46,766,923.6667
If the quotient is a whole number, then 3 and 46,766,923.6667 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 | 140,300,771 | |
| -1 | -140,300,771 |
Let's try dividing by 4:
140,300,771 ÷ 4 = 35,075,192.75
If the quotient is a whole number, then 4 and 35,075,192.75 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 | 140,300,771 | |
| -1 | 140,300,771 |
If you did it right, you will end up with this table:
| 1 | 13 | 193 | 199 | 281 | 2,509 | 2,587 | 3,653 | 38,407 | 54,233 | 55,919 | 499,291 | 705,029 | 726,947 | 10,792,367 | 140,300,771 |
| -1 | -13 | -193 | -199 | -281 | -2,509 | -2,587 | -3,653 | -38,407 | -54,233 | -55,919 | -499,291 | -705,029 | -726,947 | -10,792,367 | -140,300,771 |
