Hey !
Given that the smallest number when divided by 28 and 32 leaves remainder 8 and 12 respectively.
28 - 8 = 20 and 32 - 12 = 20 are divisible by the required numbers.
Therefore the required number will be 20 less than the LCM of 28 and 32.
Prime factorization of 28 = 2 * 2 * 7
Prime factorization of 32 = 2 * 2 * 2 * 2 * 2
LCM(28,32) = 2 * 2 * 2 * 2 * 2 * 7
= 224.
Therefore the required smallest number = 224 - 20
= 204.
