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 75,601,025, 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 | 75,601,025 | |
| -1 | -75,601,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,601,025.
Example:
1 x 75,601,025 = 75,601,025
and
-1 x -75,601,025 = 75,601,025
Notice both answers equal 75,601,025
With that explanation out of the way, let's continue. Next, we take the number 75,601,025 and divide it by 2:
75,601,025 ÷ 2 = 37,800,512.5
If the quotient is a whole number, then 2 and 37,800,512.5 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 | 75,601,025 | |
| -1 | -75,601,025 |
Now, we try dividing 75,601,025 by 3:
75,601,025 ÷ 3 = 25,200,341.6667
If the quotient is a whole number, then 3 and 25,200,341.6667 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 | 75,601,025 | |
| -1 | -75,601,025 |
Let's try dividing by 4:
75,601,025 ÷ 4 = 18,900,256.25
If the quotient is a whole number, then 4 and 18,900,256.25 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 | 75,601,025 | |
| -1 | 75,601,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 79 | 101 | 379 | 395 | 505 | 1,895 | 1,975 | 2,525 | 7,979 | 9,475 | 29,941 | 38,279 | 39,895 | 149,705 | 191,395 | 199,475 | 748,525 | 956,975 | 3,024,041 | 15,120,205 | 75,601,025 |
| -1 | -5 | -25 | -79 | -101 | -379 | -395 | -505 | -1,895 | -1,975 | -2,525 | -7,979 | -9,475 | -29,941 | -38,279 | -39,895 | -149,705 | -191,395 | -199,475 | -748,525 | -956,975 | -3,024,041 | -15,120,205 | -75,601,025 |
