alleryWhich numbers are the proper divisors of 6?
A1, 2 and 3
B1, 2, 3 and 6
C2 and 3
D1 and 6
Answer & Solution
Correct answer: A. 1, 2 and 3
1. Proper divisors exclude the number itself.
2. For 6 these are 1, 2 and 3, and 1 + 2 + 3 = 6.
3. Listing 6 itself is wrong, and 2 and 3 alone miss the divisor 1.
