Answer 2

Answer:

L.C.M of (15  20 30 40 50 60) = 600

smallest 6=digit number is=100000

if we 100000/600

leaves remainder 400

hence, 100000+(600-400)

=100200 - (this is exactly divisible by ,15 20 30 40 50 60)

{ e.g 100200/600= 167, leaves remainder =0}

now,

100200+7 = 100207 is the smallest 6-digit number which on diminished by 7 , [ 100207-7 = 100200 , which is divisible by 15 20 30 40 50 60  ] , is exactly divisible by 15 20 30 40 50 60.

you can verify it by dividing with each number.
