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 238,601,965, 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 | 238,601,965 | |
| -1 | -238,601,965 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 238,601,965.
Example:
1 x 238,601,965 = 238,601,965
and
-1 x -238,601,965 = 238,601,965
Notice both answers equal 238,601,965
With that explanation out of the way, let's continue. Next, we take the number 238,601,965 and divide it by 2:
238,601,965 ÷ 2 = 119,300,982.5
If the quotient is a whole number, then 2 and 119,300,982.5 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 | 238,601,965 | |
| -1 | -238,601,965 |
Now, we try dividing 238,601,965 by 3:
238,601,965 ÷ 3 = 79,533,988.3333
If the quotient is a whole number, then 3 and 79,533,988.3333 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 | 238,601,965 | |
| -1 | -238,601,965 |
Let's try dividing by 4:
238,601,965 ÷ 4 = 59,650,491.25
If the quotient is a whole number, then 4 and 59,650,491.25 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 | 238,601,965 | |
| -1 | 238,601,965 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 211 | 1,055 | 1,477 | 7,385 | 32,309 | 161,545 | 226,163 | 1,130,815 | 6,817,199 | 34,085,995 | 47,720,393 | 238,601,965 |
| -1 | -5 | -7 | -35 | -211 | -1,055 | -1,477 | -7,385 | -32,309 | -161,545 | -226,163 | -1,130,815 | -6,817,199 | -34,085,995 | -47,720,393 | -238,601,965 |
