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 372,536,011, 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 | 372,536,011 | |
| -1 | -372,536,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 372,536,011.
Example:
1 x 372,536,011 = 372,536,011
and
-1 x -372,536,011 = 372,536,011
Notice both answers equal 372,536,011
With that explanation out of the way, let's continue. Next, we take the number 372,536,011 and divide it by 2:
372,536,011 ÷ 2 = 186,268,005.5
If the quotient is a whole number, then 2 and 186,268,005.5 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 | 372,536,011 | |
| -1 | -372,536,011 |
Now, we try dividing 372,536,011 by 3:
372,536,011 ÷ 3 = 124,178,670.3333
If the quotient is a whole number, then 3 and 124,178,670.3333 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 | 372,536,011 | |
| -1 | -372,536,011 |
Let's try dividing by 4:
372,536,011 ÷ 4 = 93,134,002.75
If the quotient is a whole number, then 4 and 93,134,002.75 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 | 372,536,011 | |
| -1 | 372,536,011 |
If you did it right, you will end up with this table:
| 1 | 17 | 163 | 233 | 577 | 2,771 | 3,961 | 9,809 | 37,979 | 94,051 | 134,441 | 645,643 | 1,598,867 | 2,285,497 | 21,913,883 | 372,536,011 |
| -1 | -17 | -163 | -233 | -577 | -2,771 | -3,961 | -9,809 | -37,979 | -94,051 | -134,441 | -645,643 | -1,598,867 | -2,285,497 | -21,913,883 | -372,536,011 |
