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 262,262,611, 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 | 262,262,611 | |
| -1 | -262,262,611 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 262,262,611.
Example:
1 x 262,262,611 = 262,262,611
and
-1 x -262,262,611 = 262,262,611
Notice both answers equal 262,262,611
With that explanation out of the way, let's continue. Next, we take the number 262,262,611 and divide it by 2:
262,262,611 ÷ 2 = 131,131,305.5
If the quotient is a whole number, then 2 and 131,131,305.5 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 | 262,262,611 | |
| -1 | -262,262,611 |
Now, we try dividing 262,262,611 by 3:
262,262,611 ÷ 3 = 87,420,870.3333
If the quotient is a whole number, then 3 and 87,420,870.3333 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 | 262,262,611 | |
| -1 | -262,262,611 |
Let's try dividing by 4:
262,262,611 ÷ 4 = 65,565,652.75
If the quotient is a whole number, then 4 and 65,565,652.75 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 | 262,262,611 | |
| -1 | 262,262,611 |
If you did it right, you will end up with this table:
| 1 | 13 | 59 | 109 | 767 | 1,417 | 3,137 | 6,431 | 40,781 | 83,603 | 185,083 | 341,933 | 2,406,079 | 4,445,129 | 20,174,047 | 262,262,611 |
| -1 | -13 | -59 | -109 | -767 | -1,417 | -3,137 | -6,431 | -40,781 | -83,603 | -185,083 | -341,933 | -2,406,079 | -4,445,129 | -20,174,047 | -262,262,611 |
