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 761,504,429, 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 | 761,504,429 | |
| -1 | -761,504,429 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 761,504,429.
Example:
1 x 761,504,429 = 761,504,429
and
-1 x -761,504,429 = 761,504,429
Notice both answers equal 761,504,429
With that explanation out of the way, let's continue. Next, we take the number 761,504,429 and divide it by 2:
761,504,429 ÷ 2 = 380,752,214.5
If the quotient is a whole number, then 2 and 380,752,214.5 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 | 761,504,429 | |
| -1 | -761,504,429 |
Now, we try dividing 761,504,429 by 3:
761,504,429 ÷ 3 = 253,834,809.6667
If the quotient is a whole number, then 3 and 253,834,809.6667 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 | 761,504,429 | |
| -1 | -761,504,429 |
Let's try dividing by 4:
761,504,429 ÷ 4 = 190,376,107.25
If the quotient is a whole number, then 4 and 190,376,107.25 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 | 761,504,429 | |
| -1 | 761,504,429 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 217 | 239 | 1,673 | 7,409 | 14,683 | 51,863 | 102,781 | 455,173 | 3,186,211 | 3,509,237 | 24,564,659 | 108,786,347 | 761,504,429 |
| -1 | -7 | -31 | -217 | -239 | -1,673 | -7,409 | -14,683 | -51,863 | -102,781 | -455,173 | -3,186,211 | -3,509,237 | -24,564,659 | -108,786,347 | -761,504,429 |
