Answer 2

According to Euclid's Division Lemma =>

Euclid's Division Lemma =>

a=b×q+r , Where r is not equal to zero

Apply Euclid's Division Lemma on 420 and 130 

420=130 x 3+30

As r≠ 0 apply again Euclid's division Lemma on 130 and 30 .

130= 30 X 4+10

As r≠ 0 apply again Euclid's division Lemma on 30 and 10

30 = 10 X 3 + 0

As r=0 , HCF = 10 

$\boxed{Therefore\:HCF\:of\:420\:and\:130\:=\:10}$
