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 140,728,763, 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 | 140,728,763 | |
| -1 | -140,728,763 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,728,763.
Example:
1 x 140,728,763 = 140,728,763
and
-1 x -140,728,763 = 140,728,763
Notice both answers equal 140,728,763
With that explanation out of the way, let's continue. Next, we take the number 140,728,763 and divide it by 2:
140,728,763 ÷ 2 = 70,364,381.5
If the quotient is a whole number, then 2 and 70,364,381.5 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 | 140,728,763 | |
| -1 | -140,728,763 |
Now, we try dividing 140,728,763 by 3:
140,728,763 ÷ 3 = 46,909,587.6667
If the quotient is a whole number, then 3 and 46,909,587.6667 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 | 140,728,763 | |
| -1 | -140,728,763 |
Let's try dividing by 4:
140,728,763 ÷ 4 = 35,182,190.75
If the quotient is a whole number, then 4 and 35,182,190.75 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 | 140,728,763 | |
| -1 | 140,728,763 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 47 | 133 | 329 | 479 | 893 | 2,209 | 3,353 | 6,251 | 9,101 | 15,463 | 22,513 | 41,971 | 63,707 | 157,591 | 293,797 | 427,747 | 1,058,111 | 2,994,229 | 7,406,777 | 20,104,109 | 140,728,763 |
| -1 | -7 | -19 | -47 | -133 | -329 | -479 | -893 | -2,209 | -3,353 | -6,251 | -9,101 | -15,463 | -22,513 | -41,971 | -63,707 | -157,591 | -293,797 | -427,747 | -1,058,111 | -2,994,229 | -7,406,777 | -20,104,109 | -140,728,763 |
