kumari jyoti   10 years AGO

the smallest no divisible by 2,3,5,7 will be 2*3*5*7=210.
also the no has to be divisible by 100. so the required no is the one that is a multiple of 210 and divisible by 100. so, the answer is 2100.

JITENDRA PRATAP SINGH   10 years AGO

lcm of 2,3,5,7 is 210. 210 has 2,3,5,7,as its multiple or factor..but it is not divisible by 100.
further if 210 is divisible by 2,3,5,7 then (k*210) will also be divisible by 2,3,5,7,where k is an positive integer.
so to satisfy condition smallest value of k is 10.
so,required number=10*210=2100.

For a no to be divisible by 100, it should have atleast two zeros at its last.
Also, no having 2,3,5,7 as its multiple should be atleast equal to 2*3*5*7 = 210 or a multiple of 210.
The least no satisfying these two conditions is 2100. Ans.
