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 158,431,525, 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 | 158,431,525 | |
| -1 | -158,431,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 158,431,525.
Example:
1 x 158,431,525 = 158,431,525
and
-1 x -158,431,525 = 158,431,525
Notice both answers equal 158,431,525
With that explanation out of the way, let's continue. Next, we take the number 158,431,525 and divide it by 2:
158,431,525 ÷ 2 = 79,215,762.5
If the quotient is a whole number, then 2 and 79,215,762.5 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 | 158,431,525 | |
| -1 | -158,431,525 |
Now, we try dividing 158,431,525 by 3:
158,431,525 ÷ 3 = 52,810,508.3333
If the quotient is a whole number, then 3 and 52,810,508.3333 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 | 158,431,525 | |
| -1 | -158,431,525 |
Let's try dividing by 4:
158,431,525 ÷ 4 = 39,607,881.25
If the quotient is a whole number, then 4 and 39,607,881.25 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 | 158,431,525 | |
| -1 | 158,431,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 347 | 1,735 | 2,429 | 2,609 | 8,675 | 12,145 | 13,045 | 18,263 | 60,725 | 65,225 | 91,315 | 456,575 | 905,323 | 4,526,615 | 6,337,261 | 22,633,075 | 31,686,305 | 158,431,525 |
| -1 | -5 | -7 | -25 | -35 | -175 | -347 | -1,735 | -2,429 | -2,609 | -8,675 | -12,145 | -13,045 | -18,263 | -60,725 | -65,225 | -91,315 | -456,575 | -905,323 | -4,526,615 | -6,337,261 | -22,633,075 | -31,686,305 | -158,431,525 |
