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 151,033,525, 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 | 151,033,525 | |
| -1 | -151,033,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,033,525.
Example:
1 x 151,033,525 = 151,033,525
and
-1 x -151,033,525 = 151,033,525
Notice both answers equal 151,033,525
With that explanation out of the way, let's continue. Next, we take the number 151,033,525 and divide it by 2:
151,033,525 ÷ 2 = 75,516,762.5
If the quotient is a whole number, then 2 and 75,516,762.5 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 | 151,033,525 | |
| -1 | -151,033,525 |
Now, we try dividing 151,033,525 by 3:
151,033,525 ÷ 3 = 50,344,508.3333
If the quotient is a whole number, then 3 and 50,344,508.3333 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 | 151,033,525 | |
| -1 | -151,033,525 |
Let's try dividing by 4:
151,033,525 ÷ 4 = 37,758,381.25
If the quotient is a whole number, then 4 and 37,758,381.25 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 | 151,033,525 | |
| -1 | 151,033,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 25 | 85 | 115 | 391 | 425 | 575 | 1,955 | 9,775 | 15,451 | 77,255 | 262,667 | 355,373 | 386,275 | 1,313,335 | 1,776,865 | 6,041,341 | 6,566,675 | 8,884,325 | 30,206,705 | 151,033,525 |
| -1 | -5 | -17 | -23 | -25 | -85 | -115 | -391 | -425 | -575 | -1,955 | -9,775 | -15,451 | -77,255 | -262,667 | -355,373 | -386,275 | -1,313,335 | -1,776,865 | -6,041,341 | -6,566,675 | -8,884,325 | -30,206,705 | -151,033,525 |
