Answer : 112
Solution: LCM of 4,7,8 is 56
The smallest 3 digit no. that can be divided by 4,7,8 will also be divided by 56.
(56*2=112)----3 digit no.

Answer :9
Explanation: LCM of 5,7 and 15 is 105
Therefore add 4 to LCM =105+4=109
So 109 is the first desired three digit no.
Three digits numbers which upon division by 5,7 and 15,give remainder of 4 are 109,214,319,424,529,634,739,844.
So 9 is the correct option.
Hence proved.
