Question

Find the greatest number of six digits exactly divisible by 15,24 and 3.(it is3 not 36)​

Answer 1

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
