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 144,422,525, 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 | 144,422,525 | |
| -1 | -144,422,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,422,525.
Example:
1 x 144,422,525 = 144,422,525
and
-1 x -144,422,525 = 144,422,525
Notice both answers equal 144,422,525
With that explanation out of the way, let's continue. Next, we take the number 144,422,525 and divide it by 2:
144,422,525 ÷ 2 = 72,211,262.5
If the quotient is a whole number, then 2 and 72,211,262.5 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 | 144,422,525 | |
| -1 | -144,422,525 |
Now, we try dividing 144,422,525 by 3:
144,422,525 ÷ 3 = 48,140,841.6667
If the quotient is a whole number, then 3 and 48,140,841.6667 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 | 144,422,525 | |
| -1 | -144,422,525 |
Let's try dividing by 4:
144,422,525 ÷ 4 = 36,105,631.25
If the quotient is a whole number, then 4 and 36,105,631.25 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 | 144,422,525 | |
| -1 | 144,422,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 89 | 325 | 445 | 1,157 | 2,225 | 4,993 | 5,785 | 24,965 | 28,925 | 64,909 | 124,825 | 324,545 | 444,377 | 1,622,725 | 2,221,885 | 5,776,901 | 11,109,425 | 28,884,505 | 144,422,525 |
| -1 | -5 | -13 | -25 | -65 | -89 | -325 | -445 | -1,157 | -2,225 | -4,993 | -5,785 | -24,965 | -28,925 | -64,909 | -124,825 | -324,545 | -444,377 | -1,622,725 | -2,221,885 | -5,776,901 | -11,109,425 | -28,884,505 | -144,422,525 |
