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 77,088,229, 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 | 77,088,229 | |
-1 | -77,088,229 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 77,088,229.
Example:
1 x 77,088,229 = 77,088,229
and
-1 x -77,088,229 = 77,088,229
Notice both answers equal 77,088,229
With that explanation out of the way, let's continue. Next, we take the number 77,088,229 and divide it by 2:
77,088,229 ÷ 2 = 38,544,114.5
If the quotient is a whole number, then 2 and 38,544,114.5 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 | 77,088,229 | |
-1 | -77,088,229 |
Now, we try dividing 77,088,229 by 3:
77,088,229 ÷ 3 = 25,696,076.3333
If the quotient is a whole number, then 3 and 25,696,076.3333 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 | 77,088,229 | |
-1 | -77,088,229 |
Let's try dividing by 4:
77,088,229 ÷ 4 = 19,272,057.25
If the quotient is a whole number, then 4 and 19,272,057.25 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 | 77,088,229 | |
-1 | 77,088,229 |
If you did it right, you will end up with this table:
1 | 431 | 178,859 | 77,088,229 |
-1 | -431 | -178,859 | -77,088,229 |
