For https://scratch.mit.edu/discuss/topic/504048/ Press space to enter a new number. Project outputs all of the factors or divisors of a number. A new change significantly reduces the time needed to calculate all the factors (it only needs to check 960,000 numbers to calculate all factors for 900,000,000,000) as it doesn't need to check for the dual of factors already calculated. However, the square roots of perfect squares are listed twice.
