Explanation:
factorise the above numbers:
8=2^3
12=2^2×3
7=7
In the above question,
there are two 7 and two 8 from which we have to write only one 7 and one 8 as takeing common we write 8,12,7,8,7 as 8,12,7
Then,
L.C.M=2^3×3×7
=168
In L.C.M ,we take both common as well as remaining numbers but in H.C.F,we take only common numbers .
