Answer 2

Thus, the HCF of 28,32,40 is 4.

Given:

28,32,40.

To find:

Their HCF.

Solution:

To determine the HCF of 28,32,40 we have to follow the below steps follows-

28,32,40 can be written in terms of their factors as follows-

$28 = 7 \times 2 \times 2 \\ 32 \times 2 \times 2 \times 2 \times 2 \times 2 \\ 40 = 2 \times 2 \times 2 \times 5$

Thus highest common factor is 2×2=4.

Thus, the HCF of 28,32,40 is 4.
