Hello friend,
Here's your answer:

First step is to do prime Factorization of the given numbers:

20 = 2 × 2 × 5
30 = 2 × 15
40 = (2 × 20) = 2 × 2 × 2 × 5

Second step is to take the common numbers out of the given prime factors.

1 number of 2 is common in all the numbers.
Therefore 2 is the HCF of 20, 30, 40.
