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 145,027,057, 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 | 145,027,057 | |
| -1 | -145,027,057 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,027,057.
Example:
1 x 145,027,057 = 145,027,057
and
-1 x -145,027,057 = 145,027,057
Notice both answers equal 145,027,057
With that explanation out of the way, let's continue. Next, we take the number 145,027,057 and divide it by 2:
145,027,057 ÷ 2 = 72,513,528.5
If the quotient is a whole number, then 2 and 72,513,528.5 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 | 145,027,057 | |
| -1 | -145,027,057 |
Now, we try dividing 145,027,057 by 3:
145,027,057 ÷ 3 = 48,342,352.3333
If the quotient is a whole number, then 3 and 48,342,352.3333 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 | 145,027,057 | |
| -1 | -145,027,057 |
Let's try dividing by 4:
145,027,057 ÷ 4 = 36,256,764.25
If the quotient is a whole number, then 4 and 36,256,764.25 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 | 145,027,057 | |
| -1 | 145,027,057 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 29 | 133 | 203 | 361 | 551 | 1,979 | 2,527 | 3,857 | 10,469 | 13,853 | 37,601 | 57,391 | 73,283 | 263,207 | 401,737 | 714,419 | 1,090,429 | 5,000,933 | 7,633,003 | 20,718,151 | 145,027,057 |
| -1 | -7 | -19 | -29 | -133 | -203 | -361 | -551 | -1,979 | -2,527 | -3,857 | -10,469 | -13,853 | -37,601 | -57,391 | -73,283 | -263,207 | -401,737 | -714,419 | -1,090,429 | -5,000,933 | -7,633,003 | -20,718,151 | -145,027,057 |
