Product of two co-prime numbers is 117. Their L.C.M should be__________?
Correct answer: B. 117
- A. 1
- B. 117
- C. equal to their H.C.F
- D. Cannot be calculated
Explanation
For coprime numbers, the HCF is 1, so their LCM equals their product. Hence the LCM is 117, since the product is 117. The likely mistake is choosing 1 because it is their HCF, confusing the greatest common divisor with the least common multiple.
