❇Find the lcm and hcf of the following numbers

(a)48, 72

(b)33,110

(c)21,24,36

(d)15,25,30

$\large\purple{\underline{{\boxed{\textsf{First\:48,\:72}}}}}$

➡48= 2 x 2 x 2 x 2 x 3

➡72= 2 x 2 x 2 x 3 x 3

❇HCF= 2 x 2 x 2 x3 = 24

✴LCM= 2 x 2 x 2 x 3 x 2 x 3= 144

$\large\blue{\underline{{\boxed{\textsf{Second\:33\:110}}}}}$

➡33= 3 x 11

➡110= 2 x 5 x 11

❇HCF= 11

✴LCM= 11 x 2 x 5 x 3= 360

$\large\green{\underline{{\boxed{\textsf{Third\:21\:24\:36}}}}}$

➡21= 7 x 3

➡24= 2 x 2 x 2 x 3

➡36= 2 x 2 x 3 x 3

❇HCF= 2 x 2 x 3= 12

✴LCM= 2 x 2 x 3 x 3 x 2 x 3 x 7= 1512

$\large\orange{\underline{{\boxed{\textsf{Fourth\:15\:25\:30}}}}}$

➡15= 3 x 5

➡25= 5 x 5

➡30=5 x 6

❇HCF= 5 x 5=25

✴LCM= 25 x 6 x 3= 450.

Hence ,completed all the sums ..❤
