Step-by-step explanation:

Subtract 6 = 144 which is divisible by 16, 18, 12 evenly. But, subtract 294, getting = -144, and you get another number divisible by 16, 18 and 12. So, a revision in the question should say, subtract the smallest number from 150 which results in a positive number evenly divisible by 16, 18, and 12.

or

For knowing the number exactly divisible by 16, 18 and 12 we need to factorize these numbers and isolate the common factors. Thus:

16=2*2*2*2

18=2*3*3

12=2*2*3

common factors=2*2*2*2*3*3=144 which is exactly divisible. So the number to be deducted is 6.
