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 145,757,185, 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 | 145,757,185 | |
| -1 | -145,757,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,757,185.
Example:
1 x 145,757,185 = 145,757,185
and
-1 x -145,757,185 = 145,757,185
Notice both answers equal 145,757,185
With that explanation out of the way, let's continue. Next, we take the number 145,757,185 and divide it by 2:
145,757,185 ÷ 2 = 72,878,592.5
If the quotient is a whole number, then 2 and 72,878,592.5 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 | 145,757,185 | |
| -1 | -145,757,185 |
Now, we try dividing 145,757,185 by 3:
145,757,185 ÷ 3 = 48,585,728.3333
If the quotient is a whole number, then 3 and 48,585,728.3333 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 | 145,757,185 | |
| -1 | -145,757,185 |
Let's try dividing by 4:
145,757,185 ÷ 4 = 36,439,296.25
If the quotient is a whole number, then 4 and 36,439,296.25 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 | 145,757,185 | |
| -1 | 145,757,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,723 | 2,417 | 8,615 | 12,061 | 12,085 | 16,919 | 60,305 | 84,595 | 4,164,491 | 20,822,455 | 29,151,437 | 145,757,185 |
| -1 | -5 | -7 | -35 | -1,723 | -2,417 | -8,615 | -12,061 | -12,085 | -16,919 | -60,305 | -84,595 | -4,164,491 | -20,822,455 | -29,151,437 | -145,757,185 |
