The sum of non-prime positive divisors of 450 is
- A 1209
- B 1299
- C 1199
- D 1099
Answer & Solution
Correct Answer
(C) 1199
Step-by-step Solution
Detailed explanation
Prime factors of 450 is \(2 \times 3 \times 3 \times 5 \times 5\). Now, non-prime divisors will be combinations of these. When two are multiplied, \(2 \times 3=6,2 \times 5=10\) \(3 \times 3=9,3 \times 5=15,5 \times 5=25\) When three are multiplied,…
