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 140,144,323, 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 | 140,144,323 | |
| -1 | -140,144,323 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,144,323.
Example:
1 x 140,144,323 = 140,144,323
and
-1 x -140,144,323 = 140,144,323
Notice both answers equal 140,144,323
With that explanation out of the way, let's continue. Next, we take the number 140,144,323 and divide it by 2:
140,144,323 ÷ 2 = 70,072,161.5
If the quotient is a whole number, then 2 and 70,072,161.5 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 | 140,144,323 | |
| -1 | -140,144,323 |
Now, we try dividing 140,144,323 by 3:
140,144,323 ÷ 3 = 46,714,774.3333
If the quotient is a whole number, then 3 and 46,714,774.3333 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 | 140,144,323 | |
| -1 | -140,144,323 |
Let's try dividing by 4:
140,144,323 ÷ 4 = 35,036,080.75
If the quotient is a whole number, then 4 and 35,036,080.75 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 | 140,144,323 | |
| -1 | 140,144,323 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 157 | 209 | 1,727 | 2,983 | 4,271 | 32,813 | 46,981 | 81,149 | 670,547 | 892,639 | 7,376,017 | 12,740,393 | 140,144,323 |
| -1 | -11 | -19 | -157 | -209 | -1,727 | -2,983 | -4,271 | -32,813 | -46,981 | -81,149 | -670,547 | -892,639 | -7,376,017 | -12,740,393 | -140,144,323 |
