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 616,275,527, 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 | 616,275,527 | |
| -1 | -616,275,527 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 616,275,527.
Example:
1 x 616,275,527 = 616,275,527
and
-1 x -616,275,527 = 616,275,527
Notice both answers equal 616,275,527
With that explanation out of the way, let's continue. Next, we take the number 616,275,527 and divide it by 2:
616,275,527 ÷ 2 = 308,137,763.5
If the quotient is a whole number, then 2 and 308,137,763.5 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 | 616,275,527 | |
| -1 | -616,275,527 |
Now, we try dividing 616,275,527 by 3:
616,275,527 ÷ 3 = 205,425,175.6667
If the quotient is a whole number, then 3 and 205,425,175.6667 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 | 616,275,527 | |
| -1 | -616,275,527 |
Let's try dividing by 4:
616,275,527 ÷ 4 = 154,068,881.75
If the quotient is a whole number, then 4 and 154,068,881.75 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 | 616,275,527 | |
| -1 | 616,275,527 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 71 | 301 | 497 | 3,053 | 21,371 | 28,837 | 201,859 | 1,239,991 | 2,047,427 | 8,679,937 | 14,331,989 | 88,039,361 | 616,275,527 |
| -1 | -7 | -43 | -71 | -301 | -497 | -3,053 | -21,371 | -28,837 | -201,859 | -1,239,991 | -2,047,427 | -8,679,937 | -14,331,989 | -88,039,361 | -616,275,527 |
