Answer:
First we need to remove LCM of 15 24 &3
That is 120.
now accordingly to the question we need a 6 digit number so we have to multiply 120 by a certain number that dancer comes in a 6 digit and must be the highest number of 6 digit which is divisible by 15 24 and 3
accordingly from the above we have multiply the number in such a way that it is 6 digit number
now 120*120
= 14400 it is a 5 digit no
14400*10=144000--6 digit no
we need greatest
144000*2=288000. (6 digit)
144000*6=864000(6 digit)
144000*6=1008000( 7 digit )
From above the required no is 86400
