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 145,152,535, 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 | 145,152,535 | |
| -1 | -145,152,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,152,535.
Example:
1 x 145,152,535 = 145,152,535
and
-1 x -145,152,535 = 145,152,535
Notice both answers equal 145,152,535
With that explanation out of the way, let's continue. Next, we take the number 145,152,535 and divide it by 2:
145,152,535 ÷ 2 = 72,576,267.5
If the quotient is a whole number, then 2 and 72,576,267.5 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 | 145,152,535 | |
| -1 | -145,152,535 |
Now, we try dividing 145,152,535 by 3:
145,152,535 ÷ 3 = 48,384,178.3333
If the quotient is a whole number, then 3 and 48,384,178.3333 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 | 145,152,535 | |
| -1 | -145,152,535 |
Let's try dividing by 4:
145,152,535 ÷ 4 = 36,288,133.75
If the quotient is a whole number, then 4 and 36,288,133.75 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 | 145,152,535 | |
| -1 | 145,152,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 1,249 | 2,113 | 6,245 | 10,565 | 13,739 | 23,243 | 68,695 | 116,215 | 2,639,137 | 13,195,685 | 29,030,507 | 145,152,535 |
| -1 | -5 | -11 | -55 | -1,249 | -2,113 | -6,245 | -10,565 | -13,739 | -23,243 | -68,695 | -116,215 | -2,639,137 | -13,195,685 | -29,030,507 | -145,152,535 |
