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 145,314,337, 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 | 145,314,337 | |
| -1 | -145,314,337 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,314,337.
Example:
1 x 145,314,337 = 145,314,337
and
-1 x -145,314,337 = 145,314,337
Notice both answers equal 145,314,337
With that explanation out of the way, let's continue. Next, we take the number 145,314,337 and divide it by 2:
145,314,337 ÷ 2 = 72,657,168.5
If the quotient is a whole number, then 2 and 72,657,168.5 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 | 145,314,337 | |
| -1 | -145,314,337 |
Now, we try dividing 145,314,337 by 3:
145,314,337 ÷ 3 = 48,438,112.3333
If the quotient is a whole number, then 3 and 48,438,112.3333 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 | 145,314,337 | |
| -1 | -145,314,337 |
Let's try dividing by 4:
145,314,337 ÷ 4 = 36,328,584.25
If the quotient is a whole number, then 4 and 36,328,584.25 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 | 145,314,337 | |
| -1 | 145,314,337 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 163 | 1,141 | 3,097 | 6,703 | 21,679 | 46,921 | 127,357 | 891,499 | 1,092,589 | 7,648,123 | 20,759,191 | 145,314,337 |
| -1 | -7 | -19 | -133 | -163 | -1,141 | -3,097 | -6,703 | -21,679 | -46,921 | -127,357 | -891,499 | -1,092,589 | -7,648,123 | -20,759,191 | -145,314,337 |
