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 147,003,571, 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 | 147,003,571 | |
| -1 | -147,003,571 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,003,571.
Example:
1 x 147,003,571 = 147,003,571
and
-1 x -147,003,571 = 147,003,571
Notice both answers equal 147,003,571
With that explanation out of the way, let's continue. Next, we take the number 147,003,571 and divide it by 2:
147,003,571 ÷ 2 = 73,501,785.5
If the quotient is a whole number, then 2 and 73,501,785.5 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 | 147,003,571 | |
| -1 | -147,003,571 |
Now, we try dividing 147,003,571 by 3:
147,003,571 ÷ 3 = 49,001,190.3333
If the quotient is a whole number, then 3 and 49,001,190.3333 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 | 147,003,571 | |
| -1 | -147,003,571 |
Let's try dividing by 4:
147,003,571 ÷ 4 = 36,750,892.75
If the quotient is a whole number, then 4 and 36,750,892.75 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 | 147,003,571 | |
| -1 | 147,003,571 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 179 | 1,969 | 2,327 | 5,743 | 25,597 | 63,173 | 74,659 | 821,249 | 1,027,997 | 11,307,967 | 13,363,961 | 147,003,571 |
| -1 | -11 | -13 | -143 | -179 | -1,969 | -2,327 | -5,743 | -25,597 | -63,173 | -74,659 | -821,249 | -1,027,997 | -11,307,967 | -13,363,961 | -147,003,571 |
