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 77,026,201, 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 | 77,026,201 | |
| -1 | -77,026,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 77,026,201.
Example:
1 x 77,026,201 = 77,026,201
and
-1 x -77,026,201 = 77,026,201
Notice both answers equal 77,026,201
With that explanation out of the way, let's continue. Next, we take the number 77,026,201 and divide it by 2:
77,026,201 ÷ 2 = 38,513,100.5
If the quotient is a whole number, then 2 and 38,513,100.5 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 | 77,026,201 | |
| -1 | -77,026,201 |
Now, we try dividing 77,026,201 by 3:
77,026,201 ÷ 3 = 25,675,400.3333
If the quotient is a whole number, then 3 and 25,675,400.3333 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 | 77,026,201 | |
| -1 | -77,026,201 |
Let's try dividing by 4:
77,026,201 ÷ 4 = 19,256,550.25
If the quotient is a whole number, then 4 and 19,256,550.25 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 | 77,026,201 | |
| -1 | 77,026,201 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 43 | 119 | 301 | 731 | 5,117 | 15,053 | 105,371 | 255,901 | 647,279 | 1,791,307 | 4,530,953 | 11,003,743 | 77,026,201 |
| -1 | -7 | -17 | -43 | -119 | -301 | -731 | -5,117 | -15,053 | -105,371 | -255,901 | -647,279 | -1,791,307 | -4,530,953 | -11,003,743 | -77,026,201 |
