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 612,741,325, 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 | 612,741,325 | |
| -1 | -612,741,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,741,325.
Example:
1 x 612,741,325 = 612,741,325
and
-1 x -612,741,325 = 612,741,325
Notice both answers equal 612,741,325
With that explanation out of the way, let's continue. Next, we take the number 612,741,325 and divide it by 2:
612,741,325 ÷ 2 = 306,370,662.5
If the quotient is a whole number, then 2 and 306,370,662.5 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 | 612,741,325 | |
| -1 | -612,741,325 |
Now, we try dividing 612,741,325 by 3:
612,741,325 ÷ 3 = 204,247,108.3333
If the quotient is a whole number, then 3 and 204,247,108.3333 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 | 612,741,325 | |
| -1 | -612,741,325 |
Let's try dividing by 4:
612,741,325 ÷ 4 = 153,185,331.25
If the quotient is a whole number, then 4 and 153,185,331.25 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 | 612,741,325 | |
| -1 | 612,741,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 500,197 | 2,500,985 | 3,501,379 | 12,504,925 | 17,506,895 | 24,509,653 | 87,534,475 | 122,548,265 | 612,741,325 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -500,197 | -2,500,985 | -3,501,379 | -12,504,925 | -17,506,895 | -24,509,653 | -87,534,475 | -122,548,265 | -612,741,325 |
