Many people would get confuse doing this question and might take out the HCF for these three numbers and would not then be able to solve it.
What we have to do is to find out the LCM of these three numbers and then calculate whether it comes out to be a five digit number or not.
So the LCM of these three numbers comes out to be 110.
NOw we can have any 5 digit number that is a multiple of 110. For example 11000 is a possible 5 digit number.
