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 761,737,445, 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 | 761,737,445 | |
| -1 | -761,737,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 761,737,445.
Example:
1 x 761,737,445 = 761,737,445
and
-1 x -761,737,445 = 761,737,445
Notice both answers equal 761,737,445
With that explanation out of the way, let's continue. Next, we take the number 761,737,445 and divide it by 2:
761,737,445 ÷ 2 = 380,868,722.5
If the quotient is a whole number, then 2 and 380,868,722.5 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 | 761,737,445 | |
| -1 | -761,737,445 |
Now, we try dividing 761,737,445 by 3:
761,737,445 ÷ 3 = 253,912,481.6667
If the quotient is a whole number, then 3 and 253,912,481.6667 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 | 761,737,445 | |
| -1 | -761,737,445 |
Let's try dividing by 4:
761,737,445 ÷ 4 = 190,434,361.25
If the quotient is a whole number, then 4 and 190,434,361.25 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 | 761,737,445 | |
| -1 | 761,737,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 1,280,231 | 6,401,155 | 8,961,617 | 21,763,927 | 44,808,085 | 108,819,635 | 152,347,489 | 761,737,445 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -1,280,231 | -6,401,155 | -8,961,617 | -21,763,927 | -44,808,085 | -108,819,635 | -152,347,489 | -761,737,445 |
