Answer:given,
Number = 12x and12y
where x and y are prime to each other
now,
12x × 12y= 2160
=>xy= 2160/12×12
= 15
° . ° 15= 3×15,1× 15
possible pairs =( 36,60),(12,80) ,hence answer is 2
..........
............
now we get
product of the two numbers/HCF of the two numbers
=2160/12
=180
ANS:-180
Step-by-step explanation:
Product of 2 no.s= HCF*LCM
2160=12*LCM
LCM=2160/12
LCM=180
