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 152,003,425, 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 | 152,003,425 | |
| -1 | -152,003,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,003,425.
Example:
1 x 152,003,425 = 152,003,425
and
-1 x -152,003,425 = 152,003,425
Notice both answers equal 152,003,425
With that explanation out of the way, let's continue. Next, we take the number 152,003,425 and divide it by 2:
152,003,425 ÷ 2 = 76,001,712.5
If the quotient is a whole number, then 2 and 76,001,712.5 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 | 152,003,425 | |
| -1 | -152,003,425 |
Now, we try dividing 152,003,425 by 3:
152,003,425 ÷ 3 = 50,667,808.3333
If the quotient is a whole number, then 3 and 50,667,808.3333 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 | 152,003,425 | |
| -1 | -152,003,425 |
Let's try dividing by 4:
152,003,425 ÷ 4 = 38,000,856.25
If the quotient is a whole number, then 4 and 38,000,856.25 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 | 152,003,425 | |
| -1 | 152,003,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 677 | 1,283 | 3,385 | 4,739 | 6,415 | 8,981 | 16,925 | 23,695 | 32,075 | 44,905 | 118,475 | 224,525 | 868,591 | 4,342,955 | 6,080,137 | 21,714,775 | 30,400,685 | 152,003,425 |
| -1 | -5 | -7 | -25 | -35 | -175 | -677 | -1,283 | -3,385 | -4,739 | -6,415 | -8,981 | -16,925 | -23,695 | -32,075 | -44,905 | -118,475 | -224,525 | -868,591 | -4,342,955 | -6,080,137 | -21,714,775 | -30,400,685 | -152,003,425 |
