To find HCF & LCM of two or more numbers.

Divide by prime numbers.

We note in this case, 12, & 30 are both even numbers, so they will divide by '2'.

Hence

2)12

2)6

3)3 = 1

&

2)30

3)15

5)5 = 1

First reduce both numberx to '1'.

Second;ly, we note that '2' & '3' bo appear in each set of numbers.

Hence 2 x 3 = 6 is the HCF

Having made this multiplication we are left with a '2' in the twelve and a '5' in the thirty..

Hence 6(HCF) X 2 X 5 = 60 the LCM.

Done!!!!

Hope that helps!!!!
