Answer 1

$hey \\ \\ here \: is \: the \: answer. \\ \\ lcm \: of \: 12 \: \: 15 \: \: 21 = 420 \\ \\ now \: dividing \: 300000 \: by \: 420 \\ \\ we \: get \: 714 \: as \: quotient \: and \: some \: reminder \\ \\ so \: \: no. \: greater \: than \: 300000 \: and \: \\ exactly \: divisible \: by \: 12 \: \: 15 \: \: 21 \: \\ will \: leave \: a \: quotient \: of \: \: 715 \: and \: zero \: reminder \\ \\ the \: required \: no. \: is \: 715 \times 420 = 300300. \\ \\ thanks.$
