Answer 1

Answer: THIS should be easy........

a. LCM of 74088:

2l74088

2l37044

2l18522

3l9621

3l3087

3l1029

7l343

7l49

7l7

1l1

Here, 74088=2×2×2×3×3×3×7×7×7, i.e.,

74088=$2^{3} *3^{3} *7^{3}$, which is nothing but,

74088=$(2*3*7)^{3}$,

74088=$42^{3}$,

$\sqrt[3]{74088} =42$.

∴Answer=2 digits.

Similarly, do the second bit.
