Answer 2

The HCF of 90,128 and 144 is 2

Solution:

We need to find the H.C.F that is highest common factor of 90, 128, 144

The largest common factor of two or more numbers is called the highest common factor (HCF)

First finding prime factorization of given numbers

$\begin{array}{l}{90=2 \times 3 \times 3 \times 5} \\ {128=2 \times 2 \times 2 \times 2 \times 2 \times 2} \\ {144=2 \times 2 \times 2 \times 2 \times 3 \times 3}\end{array}$

So only 2 is common in prime factors of 90, 128 and 144.

Hence HCF of 90, 128 and 144 is 2.
