Question

50 people work in a cooperative society. They all use their own conveyance. 20 people use their scooters, 12 go by their cars, 16 go by public transport and 2 use bicycles.(a) Find HCF of 20, 12, 16 and 2.
(b) One day they all decided to go by public transport which value is shown by them?

Answer 1

This is pretty easy! Now, do the prime factorization method for all of these numbers. You will see one common number in each of them.
That number is 2. Thus, that is the HCF as:-
20= 5*2*2
16= 2*2*2*2
12= 2*2*3
2 = 2

Value:-
They care for their environment or something suitable.

Answer 2

Answer:

(a) HCF(20, 12, 16, 2)= 2.(b) Eco friendly or climate friendly, energy saving.

Step-by-step explanation:

Given:

50 people using their our conveyance.

20 people use scooter, 12  people use their cars, 16 go by public transport,2 use bicycles.

They all decided to go by public transport one day.

To find:

(a) HCF of 20, 12, 16, 2.

(b) The value shown by them by deciding to go by public transport.

Solution:

(a) HCF is the highest common factor.

To find the HCF we use prime factorisation of given 4 numbers.

Then 20 = 2×2×5

        12 = 2×2×3

       16 = 2×2×2×2

       2 = 2

common prime factor is 2.

Therefore hcf(20,12,16,2) = 2.

(b) The value shown by them by choosing public transport is eco friendly or climate friendly. It can also called as energy-saving.
