Greatest Common Divisor of two numbers is 8 while their Least Common Multiple is 144. Find the other number if one number is 16.
Correct answer: C. 72
- A. 108
- B. 96
- C. 72
- D. 36
Explanation
For two numbers, product = GCD x LCM, so their product is 8 x 144 = 1152. If one number is 16, the other is 1152 ÷ 16 = 72. The likely mistake is choosing 96 by using only part of the LCM relationship instead of the product formula.
