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 77,558,063, 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 | 77,558,063 | |
| -1 | -77,558,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 77,558,063.
Example:
1 x 77,558,063 = 77,558,063
and
-1 x -77,558,063 = 77,558,063
Notice both answers equal 77,558,063
With that explanation out of the way, let's continue. Next, we take the number 77,558,063 and divide it by 2:
77,558,063 ÷ 2 = 38,779,031.5
If the quotient is a whole number, then 2 and 38,779,031.5 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 | 77,558,063 | |
| -1 | -77,558,063 |
Now, we try dividing 77,558,063 by 3:
77,558,063 ÷ 3 = 25,852,687.6667
If the quotient is a whole number, then 3 and 25,852,687.6667 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 | 77,558,063 | |
| -1 | -77,558,063 |
Let's try dividing by 4:
77,558,063 ÷ 4 = 19,389,515.75
If the quotient is a whole number, then 4 and 19,389,515.75 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 | 77,558,063 | |
| -1 | 77,558,063 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 31 | 187 | 289 | 341 | 527 | 787 | 3,179 | 5,797 | 8,657 | 8,959 | 13,379 | 24,397 | 98,549 | 147,169 | 227,443 | 268,367 | 414,749 | 2,501,873 | 4,562,239 | 7,050,733 | 77,558,063 |
| -1 | -11 | -17 | -31 | -187 | -289 | -341 | -527 | -787 | -3,179 | -5,797 | -8,657 | -8,959 | -13,379 | -24,397 | -98,549 | -147,169 | -227,443 | -268,367 | -414,749 | -2,501,873 | -4,562,239 | -7,050,733 | -77,558,063 |
