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 372,357,349, 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 | 372,357,349 | |
| -1 | -372,357,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 372,357,349.
Example:
1 x 372,357,349 = 372,357,349
and
-1 x -372,357,349 = 372,357,349
Notice both answers equal 372,357,349
With that explanation out of the way, let's continue. Next, we take the number 372,357,349 and divide it by 2:
372,357,349 ÷ 2 = 186,178,674.5
If the quotient is a whole number, then 2 and 186,178,674.5 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 | 372,357,349 | |
| -1 | -372,357,349 |
Now, we try dividing 372,357,349 by 3:
372,357,349 ÷ 3 = 124,119,116.3333
If the quotient is a whole number, then 3 and 124,119,116.3333 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 | 372,357,349 | |
| -1 | -372,357,349 |
Let's try dividing by 4:
372,357,349 ÷ 4 = 93,089,337.25
If the quotient is a whole number, then 4 and 93,089,337.25 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 | 372,357,349 | |
| -1 | 372,357,349 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 991 | 4,129 | 6,937 | 12,883 | 28,903 | 53,677 | 90,181 | 375,739 | 4,091,839 | 28,642,873 | 53,193,907 | 372,357,349 |
| -1 | -7 | -13 | -91 | -991 | -4,129 | -6,937 | -12,883 | -28,903 | -53,677 | -90,181 | -375,739 | -4,091,839 | -28,642,873 | -53,193,907 | -372,357,349 |
