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 77,602,723, 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 | 77,602,723 | |
| -1 | -77,602,723 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 77,602,723.
Example:
1 x 77,602,723 = 77,602,723
and
-1 x -77,602,723 = 77,602,723
Notice both answers equal 77,602,723
With that explanation out of the way, let's continue. Next, we take the number 77,602,723 and divide it by 2:
77,602,723 ÷ 2 = 38,801,361.5
If the quotient is a whole number, then 2 and 38,801,361.5 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 | 77,602,723 | |
| -1 | -77,602,723 |
Now, we try dividing 77,602,723 by 3:
77,602,723 ÷ 3 = 25,867,574.3333
If the quotient is a whole number, then 3 and 25,867,574.3333 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 | 77,602,723 | |
| -1 | -77,602,723 |
Let's try dividing by 4:
77,602,723 ÷ 4 = 19,400,680.75
If the quotient is a whole number, then 4 and 19,400,680.75 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 | 77,602,723 | |
| -1 | 77,602,723 |
If you did it right, you will end up with this table:
| 1 | 11 | 73 | 241 | 401 | 803 | 2,651 | 4,411 | 17,593 | 29,273 | 96,641 | 193,523 | 322,003 | 1,063,051 | 7,054,793 | 77,602,723 |
| -1 | -11 | -73 | -241 | -401 | -803 | -2,651 | -4,411 | -17,593 | -29,273 | -96,641 | -193,523 | -322,003 | -1,063,051 | -7,054,793 | -77,602,723 |
