12= 2×2×3( Factors of 12).................... 14= 2×7(Factors of 14)...... Now common factors in the factorization of 12 and 14 is only 2..... So HCF = 2.
1 5 1
next
39 and 91
next
45 and 75
Do it by urself ... Its really easy... Just write down the factorization and whatever is in common multiply that and if nothing is in common then HCF=1
