solution

Question:
There are three numbers. The HCF of each pair is 15 and the LCM of all the three numbers is 1890. The product of the numbers is:
Options:
A) 1890 x 15
B) 1890 x 152
C) 1890 x 153
D) 1890 x 154
Solution:
Ans: (b)

HCF=15

Hence 15 is a factor of every number

First number =15×a

Second number =15×b

Third number =15×c

LCM=15×a×b×c

Product of numbers =15 ×a ×15×b×15×c

=15×15 ×15×a×b×c=225×(15×a×b×c)=225×LCM

=152×1890
