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 141,742,175, 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 | 141,742,175 | |
| -1 | -141,742,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,742,175.
Example:
1 x 141,742,175 = 141,742,175
and
-1 x -141,742,175 = 141,742,175
Notice both answers equal 141,742,175
With that explanation out of the way, let's continue. Next, we take the number 141,742,175 and divide it by 2:
141,742,175 ÷ 2 = 70,871,087.5
If the quotient is a whole number, then 2 and 70,871,087.5 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 | 141,742,175 | |
| -1 | -141,742,175 |
Now, we try dividing 141,742,175 by 3:
141,742,175 ÷ 3 = 47,247,391.6667
If the quotient is a whole number, then 3 and 47,247,391.6667 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 | 141,742,175 | |
| -1 | -141,742,175 |
Let's try dividing by 4:
141,742,175 ÷ 4 = 35,435,543.75
If the quotient is a whole number, then 4 and 35,435,543.75 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 | 141,742,175 | |
| -1 | 141,742,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 359 | 425 | 929 | 1,795 | 4,645 | 6,103 | 8,975 | 15,793 | 23,225 | 30,515 | 78,965 | 152,575 | 333,511 | 394,825 | 1,667,555 | 5,669,687 | 8,337,775 | 28,348,435 | 141,742,175 |
| -1 | -5 | -17 | -25 | -85 | -359 | -425 | -929 | -1,795 | -4,645 | -6,103 | -8,975 | -15,793 | -23,225 | -30,515 | -78,965 | -152,575 | -333,511 | -394,825 | -1,667,555 | -5,669,687 | -8,337,775 | -28,348,435 | -141,742,175 |
