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 746,527,211, 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 | 746,527,211 | |
| -1 | -746,527,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 746,527,211.
Example:
1 x 746,527,211 = 746,527,211
and
-1 x -746,527,211 = 746,527,211
Notice both answers equal 746,527,211
With that explanation out of the way, let's continue. Next, we take the number 746,527,211 and divide it by 2:
746,527,211 ÷ 2 = 373,263,605.5
If the quotient is a whole number, then 2 and 373,263,605.5 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 | 746,527,211 | |
| -1 | -746,527,211 |
Now, we try dividing 746,527,211 by 3:
746,527,211 ÷ 3 = 248,842,403.6667
If the quotient is a whole number, then 3 and 248,842,403.6667 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 | 746,527,211 | |
| -1 | -746,527,211 |
Let's try dividing by 4:
746,527,211 ÷ 4 = 186,631,802.75
If the quotient is a whole number, then 4 and 186,631,802.75 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 | 746,527,211 | |
| -1 | 746,527,211 |
If you did it right, you will end up with this table:
| 1 | 61 | 103 | 131 | 907 | 6,283 | 7,991 | 13,493 | 55,327 | 93,421 | 118,817 | 823,073 | 5,698,681 | 7,247,837 | 12,238,151 | 746,527,211 |
| -1 | -61 | -103 | -131 | -907 | -6,283 | -7,991 | -13,493 | -55,327 | -93,421 | -118,817 | -823,073 | -5,698,681 | -7,247,837 | -12,238,151 | -746,527,211 |
