Asked in a 2025 paper

The product of two numbers is 2025 and their HCF is 15 their LCM is____________?

Correct answer: C. 135

  • A. 2040
  • B. 2010
  • C. 135
  • D. 150

Explanation

For two positive integers, product = HCF x LCM. Therefore LCM = 2025 / 15 = 135. The likely mistake is selecting 150 by using an approximate division or confusing the LCM with one of the original factors.
