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 140,011,225, 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 | 140,011,225 | |
| -1 | -140,011,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,011,225.
Example:
1 x 140,011,225 = 140,011,225
and
-1 x -140,011,225 = 140,011,225
Notice both answers equal 140,011,225
With that explanation out of the way, let's continue. Next, we take the number 140,011,225 and divide it by 2:
140,011,225 ÷ 2 = 70,005,612.5
If the quotient is a whole number, then 2 and 70,005,612.5 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 | 140,011,225 | |
| -1 | -140,011,225 |
Now, we try dividing 140,011,225 by 3:
140,011,225 ÷ 3 = 46,670,408.3333
If the quotient is a whole number, then 3 and 46,670,408.3333 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 | 140,011,225 | |
| -1 | -140,011,225 |
Let's try dividing by 4:
140,011,225 ÷ 4 = 35,002,806.25
If the quotient is a whole number, then 4 and 35,002,806.25 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 | 140,011,225 | |
| -1 | 140,011,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 139 | 215 | 695 | 937 | 1,075 | 3,475 | 4,685 | 5,977 | 23,425 | 29,885 | 40,291 | 130,243 | 149,425 | 201,455 | 651,215 | 1,007,275 | 3,256,075 | 5,600,449 | 28,002,245 | 140,011,225 |
| -1 | -5 | -25 | -43 | -139 | -215 | -695 | -937 | -1,075 | -3,475 | -4,685 | -5,977 | -23,425 | -29,885 | -40,291 | -130,243 | -149,425 | -201,455 | -651,215 | -1,007,275 | -3,256,075 | -5,600,449 | -28,002,245 | -140,011,225 |
