Expert Answers

An illustration of the letter 'A' in a speech bubbles

{ 6, 8, 10 }

First we will factor the numbers:

6= 2*3

8 = 2* 2 *2

10 = 2*5

==> L.C.M = 2*2*2*3*5 = 120

==> H.C.F = 2

 

{12, 14}

12 = 2*2*3

14= 2*7

==> L.C.M = 2*2*3*7 = 84

==> H.C.F = 2

 

{10, 15, 25}

10= 2*5

15 = 3*5

25= 5*5

==> L.C.M = 2*3*5*5 = 150

==> H.C.F = 5
