Step-by-step explanation:

32=2x2x2x2x2

144=2x2x2x2x3x3

So HCF=2x2x2x2=16

Answer 2

Answer:

HCF(32,144)= 16

Step-by-step explanation:

To find HCF of 32 and 144, first do prime factorisation of number individually,then make pairs in both.

$32 = 2 \times 2 \times 2 \times 2 \times 2 \\ \\ 144 = 2 \times 2 \times2 \times 2 \times 3 \times 3$

HCF(32,144)= 2×2×2×2

HCF(32,144)= 16
