I think it will help u

Answer 2

Step-by-step explanation:

We have to figure out highest so we have to take out  HCF.

HCF of 14,42 and 56

2 I 14     2 I 42        2 I 56

7 I 7       3 I 21         2 I 28

  I 1        7 I 7           2 I 14

                I 1            7 I 7

                                  I 1

14=2*7

42=2*3*7

56=2*2*2*7

HCF = 2*7

        =14

So the greatest no. that divide 14,42,56 exactly is 14.
