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 144,635,777, 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 | 144,635,777 | |
| -1 | -144,635,777 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,635,777.
Example:
1 x 144,635,777 = 144,635,777
and
-1 x -144,635,777 = 144,635,777
Notice both answers equal 144,635,777
With that explanation out of the way, let's continue. Next, we take the number 144,635,777 and divide it by 2:
144,635,777 ÷ 2 = 72,317,888.5
If the quotient is a whole number, then 2 and 72,317,888.5 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 | 144,635,777 | |
| -1 | -144,635,777 |
Now, we try dividing 144,635,777 by 3:
144,635,777 ÷ 3 = 48,211,925.6667
If the quotient is a whole number, then 3 and 48,211,925.6667 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 | 144,635,777 | |
| -1 | -144,635,777 |
Let's try dividing by 4:
144,635,777 ÷ 4 = 36,158,944.25
If the quotient is a whole number, then 4 and 36,158,944.25 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 | 144,635,777 | |
| -1 | 144,635,777 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 121 | 143 | 169 | 643 | 1,331 | 1,573 | 1,859 | 7,073 | 8,359 | 17,303 | 20,449 | 77,803 | 91,949 | 108,667 | 224,939 | 855,833 | 1,011,439 | 1,195,337 | 11,125,829 | 13,148,707 | 144,635,777 |
| -1 | -11 | -13 | -121 | -143 | -169 | -643 | -1,331 | -1,573 | -1,859 | -7,073 | -8,359 | -17,303 | -20,449 | -77,803 | -91,949 | -108,667 | -224,939 | -855,833 | -1,011,439 | -1,195,337 | -11,125,829 | -13,148,707 | -144,635,777 |
