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 140,343,041, 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 | 140,343,041 | |
| -1 | -140,343,041 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,343,041.
Example:
1 x 140,343,041 = 140,343,041
and
-1 x -140,343,041 = 140,343,041
Notice both answers equal 140,343,041
With that explanation out of the way, let's continue. Next, we take the number 140,343,041 and divide it by 2:
140,343,041 ÷ 2 = 70,171,520.5
If the quotient is a whole number, then 2 and 70,171,520.5 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 | 140,343,041 | |
| -1 | -140,343,041 |
Now, we try dividing 140,343,041 by 3:
140,343,041 ÷ 3 = 46,781,013.6667
If the quotient is a whole number, then 3 and 46,781,013.6667 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 | 140,343,041 | |
| -1 | -140,343,041 |
Let's try dividing by 4:
140,343,041 ÷ 4 = 35,085,760.25
If the quotient is a whole number, then 4 and 35,085,760.25 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 | 140,343,041 | |
| -1 | 140,343,041 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 271 | 697 | 743 | 4,607 | 11,111 | 12,631 | 30,463 | 188,887 | 201,353 | 517,871 | 3,423,001 | 8,255,473 | 140,343,041 |
| -1 | -17 | -41 | -271 | -697 | -743 | -4,607 | -11,111 | -12,631 | -30,463 | -188,887 | -201,353 | -517,871 | -3,423,001 | -8,255,473 | -140,343,041 |
