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 77,246,267, 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 | 77,246,267 | |
| -1 | -77,246,267 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 77,246,267.
Example:
1 x 77,246,267 = 77,246,267
and
-1 x -77,246,267 = 77,246,267
Notice both answers equal 77,246,267
With that explanation out of the way, let's continue. Next, we take the number 77,246,267 and divide it by 2:
77,246,267 ÷ 2 = 38,623,133.5
If the quotient is a whole number, then 2 and 38,623,133.5 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 | 77,246,267 | |
| -1 | -77,246,267 |
Now, we try dividing 77,246,267 by 3:
77,246,267 ÷ 3 = 25,748,755.6667
If the quotient is a whole number, then 3 and 25,748,755.6667 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 | 77,246,267 | |
| -1 | -77,246,267 |
Let's try dividing by 4:
77,246,267 ÷ 4 = 19,311,566.75
If the quotient is a whole number, then 4 and 19,311,566.75 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 | 77,246,267 | |
| -1 | 77,246,267 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 673 | 863 | 4,711 | 6,041 | 12,787 | 16,397 | 89,509 | 114,779 | 580,799 | 4,065,593 | 11,035,181 | 77,246,267 |
| -1 | -7 | -19 | -133 | -673 | -863 | -4,711 | -6,041 | -12,787 | -16,397 | -89,509 | -114,779 | -580,799 | -4,065,593 | -11,035,181 | -77,246,267 |
