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 152,411,525, 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 | 152,411,525 | |
| -1 | -152,411,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,411,525.
Example:
1 x 152,411,525 = 152,411,525
and
-1 x -152,411,525 = 152,411,525
Notice both answers equal 152,411,525
With that explanation out of the way, let's continue. Next, we take the number 152,411,525 and divide it by 2:
152,411,525 ÷ 2 = 76,205,762.5
If the quotient is a whole number, then 2 and 76,205,762.5 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 | 152,411,525 | |
| -1 | -152,411,525 |
Now, we try dividing 152,411,525 by 3:
152,411,525 ÷ 3 = 50,803,841.6667
If the quotient is a whole number, then 3 and 50,803,841.6667 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 | 152,411,525 | |
| -1 | -152,411,525 |
Let's try dividing by 4:
152,411,525 ÷ 4 = 38,102,881.25
If the quotient is a whole number, then 4 and 38,102,881.25 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 | 152,411,525 | |
| -1 | 152,411,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 101 | 175 | 505 | 707 | 2,525 | 3,535 | 8,623 | 17,675 | 43,115 | 60,361 | 215,575 | 301,805 | 870,923 | 1,509,025 | 4,354,615 | 6,096,461 | 21,773,075 | 30,482,305 | 152,411,525 |
| -1 | -5 | -7 | -25 | -35 | -101 | -175 | -505 | -707 | -2,525 | -3,535 | -8,623 | -17,675 | -43,115 | -60,361 | -215,575 | -301,805 | -870,923 | -1,509,025 | -4,354,615 | -6,096,461 | -21,773,075 | -30,482,305 | -152,411,525 |
