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 144,258,565, 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 | 144,258,565 | |
| -1 | -144,258,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 144,258,565.
Example:
1 x 144,258,565 = 144,258,565
and
-1 x -144,258,565 = 144,258,565
Notice both answers equal 144,258,565
With that explanation out of the way, let's continue. Next, we take the number 144,258,565 and divide it by 2:
144,258,565 ÷ 2 = 72,129,282.5
If the quotient is a whole number, then 2 and 72,129,282.5 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 | 144,258,565 | |
| -1 | -144,258,565 |
Now, we try dividing 144,258,565 by 3:
144,258,565 ÷ 3 = 48,086,188.3333
If the quotient is a whole number, then 3 and 48,086,188.3333 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 | 144,258,565 | |
| -1 | -144,258,565 |
Let's try dividing by 4:
144,258,565 ÷ 4 = 36,064,641.25
If the quotient is a whole number, then 4 and 36,064,641.25 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 | 144,258,565 | |
| -1 | 144,258,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 83 | 415 | 913 | 4,565 | 31,601 | 158,005 | 347,611 | 1,738,055 | 2,622,883 | 13,114,415 | 28,851,713 | 144,258,565 |
| -1 | -5 | -11 | -55 | -83 | -415 | -913 | -4,565 | -31,601 | -158,005 | -347,611 | -1,738,055 | -2,622,883 | -13,114,415 | -28,851,713 | -144,258,565 |
