Answer 1

Find 3 common multiples of 9 , 18 and 27.

SO,take out the LCM of the numbers for the first multiple.

LCM=54 ———(1)

NOW,double the LCM of the numbers for second multiple.

DOUBLE LCM=54×2

=108———(2)

NOW,triple the LCM of the numbers for the third multiple.

TRIPLE LCM=54×3

=162———(3)

THEREFORE, the multiples of 9,18,27 are:

54,108,162.
