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 145,669,525, 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 | 145,669,525 | |
| -1 | -145,669,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,669,525.
Example:
1 x 145,669,525 = 145,669,525
and
-1 x -145,669,525 = 145,669,525
Notice both answers equal 145,669,525
With that explanation out of the way, let's continue. Next, we take the number 145,669,525 and divide it by 2:
145,669,525 ÷ 2 = 72,834,762.5
If the quotient is a whole number, then 2 and 72,834,762.5 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 | 145,669,525 | |
| -1 | -145,669,525 |
Now, we try dividing 145,669,525 by 3:
145,669,525 ÷ 3 = 48,556,508.3333
If the quotient is a whole number, then 3 and 48,556,508.3333 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 | 145,669,525 | |
| -1 | -145,669,525 |
Let's try dividing by 4:
145,669,525 ÷ 4 = 36,417,381.25
If the quotient is a whole number, then 4 and 36,417,381.25 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 | 145,669,525 | |
| -1 | 145,669,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 59 | 61 | 295 | 305 | 1,475 | 1,525 | 1,619 | 3,599 | 8,095 | 17,995 | 40,475 | 89,975 | 95,521 | 98,759 | 477,605 | 493,795 | 2,388,025 | 2,468,975 | 5,826,781 | 29,133,905 | 145,669,525 |
| -1 | -5 | -25 | -59 | -61 | -295 | -305 | -1,475 | -1,525 | -1,619 | -3,599 | -8,095 | -17,995 | -40,475 | -89,975 | -95,521 | -98,759 | -477,605 | -493,795 | -2,388,025 | -2,468,975 | -5,826,781 | -29,133,905 | -145,669,525 |
