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 144,612,761, 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 | 144,612,761 | |
| -1 | -144,612,761 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,612,761.
Example:
1 x 144,612,761 = 144,612,761
and
-1 x -144,612,761 = 144,612,761
Notice both answers equal 144,612,761
With that explanation out of the way, let's continue. Next, we take the number 144,612,761 and divide it by 2:
144,612,761 ÷ 2 = 72,306,380.5
If the quotient is a whole number, then 2 and 72,306,380.5 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 | 144,612,761 | |
| -1 | -144,612,761 |
Now, we try dividing 144,612,761 by 3:
144,612,761 ÷ 3 = 48,204,253.6667
If the quotient is a whole number, then 3 and 48,204,253.6667 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 | 144,612,761 | |
| -1 | -144,612,761 |
Let's try dividing by 4:
144,612,761 ÷ 4 = 36,153,190.25
If the quotient is a whole number, then 4 and 36,153,190.25 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 | 144,612,761 | |
| -1 | 144,612,761 |
If you did it right, you will end up with this table:
| 1 | 17 | 37 | 61 | 629 | 1,037 | 2,257 | 3,769 | 38,369 | 64,073 | 139,453 | 229,909 | 2,370,701 | 3,908,453 | 8,506,633 | 144,612,761 |
| -1 | -17 | -37 | -61 | -629 | -1,037 | -2,257 | -3,769 | -38,369 | -64,073 | -139,453 | -229,909 | -2,370,701 | -3,908,453 | -8,506,633 | -144,612,761 |
