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 140,460,145, 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 | 140,460,145 | |
| -1 | -140,460,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,460,145.
Example:
1 x 140,460,145 = 140,460,145
and
-1 x -140,460,145 = 140,460,145
Notice both answers equal 140,460,145
With that explanation out of the way, let's continue. Next, we take the number 140,460,145 and divide it by 2:
140,460,145 ÷ 2 = 70,230,072.5
If the quotient is a whole number, then 2 and 70,230,072.5 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 | 140,460,145 | |
| -1 | -140,460,145 |
Now, we try dividing 140,460,145 by 3:
140,460,145 ÷ 3 = 46,820,048.3333
If the quotient is a whole number, then 3 and 46,820,048.3333 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 | 140,460,145 | |
| -1 | -140,460,145 |
Let's try dividing by 4:
140,460,145 ÷ 4 = 35,115,036.25
If the quotient is a whole number, then 4 and 35,115,036.25 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 | 140,460,145 | |
| -1 | 140,460,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 1,505 | 93,329 | 466,645 | 653,303 | 3,266,515 | 4,013,147 | 20,065,735 | 28,092,029 | 140,460,145 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -1,505 | -93,329 | -466,645 | -653,303 | -3,266,515 | -4,013,147 | -20,065,735 | -28,092,029 | -140,460,145 |
