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 144,560,773, 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 | 144,560,773 | |
| -1 | -144,560,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,560,773.
Example:
1 x 144,560,773 = 144,560,773
and
-1 x -144,560,773 = 144,560,773
Notice both answers equal 144,560,773
With that explanation out of the way, let's continue. Next, we take the number 144,560,773 and divide it by 2:
144,560,773 ÷ 2 = 72,280,386.5
If the quotient is a whole number, then 2 and 72,280,386.5 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 | 144,560,773 | |
| -1 | -144,560,773 |
Now, we try dividing 144,560,773 by 3:
144,560,773 ÷ 3 = 48,186,924.3333
If the quotient is a whole number, then 3 and 48,186,924.3333 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 | 144,560,773 | |
| -1 | -144,560,773 |
Let's try dividing by 4:
144,560,773 ÷ 4 = 36,140,193.25
If the quotient is a whole number, then 4 and 36,140,193.25 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 | 144,560,773 | |
| -1 | 144,560,773 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 823 | 1,091 | 5,761 | 7,637 | 18,929 | 25,093 | 132,503 | 175,651 | 897,893 | 6,285,251 | 20,651,539 | 144,560,773 |
| -1 | -7 | -23 | -161 | -823 | -1,091 | -5,761 | -7,637 | -18,929 | -25,093 | -132,503 | -175,651 | -897,893 | -6,285,251 | -20,651,539 | -144,560,773 |
