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 140,455,601, 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 | 140,455,601 | |
| -1 | -140,455,601 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,455,601.
Example:
1 x 140,455,601 = 140,455,601
and
-1 x -140,455,601 = 140,455,601
Notice both answers equal 140,455,601
With that explanation out of the way, let's continue. Next, we take the number 140,455,601 and divide it by 2:
140,455,601 ÷ 2 = 70,227,800.5
If the quotient is a whole number, then 2 and 70,227,800.5 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 | 140,455,601 | |
| -1 | -140,455,601 |
Now, we try dividing 140,455,601 by 3:
140,455,601 ÷ 3 = 46,818,533.6667
If the quotient is a whole number, then 3 and 46,818,533.6667 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 | 140,455,601 | |
| -1 | -140,455,601 |
Let's try dividing by 4:
140,455,601 ÷ 4 = 35,113,900.25
If the quotient is a whole number, then 4 and 35,113,900.25 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 | 140,455,601 | |
| -1 | 140,455,601 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 79 | 143 | 869 | 1,027 | 11,297 | 12,433 | 136,763 | 161,629 | 982,207 | 1,777,919 | 10,804,277 | 12,768,691 | 140,455,601 |
| -1 | -11 | -13 | -79 | -143 | -869 | -1,027 | -11,297 | -12,433 | -136,763 | -161,629 | -982,207 | -1,777,919 | -10,804,277 | -12,768,691 | -140,455,601 |
