Khoisnam figured it out by realizing that lockers toggled an odd number of times would remain open. Only perfect square numbers have an odd number of factors. So, locker numbers that are perfect squares remain open at the end. Class 8 ...
No, not every number has an even number of factors. Most numbers do, but perfect square numbers have an odd number of factors because one factor (like 6 in 36) is repeated and does not pair with a different number. Class ...
Yes, using this insight, we can find all numbers that are perfect squares because they alone have an odd number of factors. Examples include 1, 4, 9, 16, 25 and so on, where one factor repeats in the pair. Class 8 ...
