wrong (Question: 117172.0 )

product will be hcf^n-1*lcm
B is the ans

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) None of these
Solution:
Ans: (a) 

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

=225 × 1890 = 425250
