Answer 1

Step-by-step explanation:

(i) 84,144

a= bq+r

144 = 84(1)+60

84 = 60(1)+12

60= 12 (5)+0

HCF = 12

(ii) 120,168

a=bq+r

168= 120(1)+68

120= 68(1)+52

68=52(1)+16

52= 16(3)+4

16= 4(4)+0

HCF = 4

(iii)430,516,817

a=bq+r

516=430(1)+86

430= 86(5)+0

HCF = 86

86,817

a= bq+r

817 = 86(9)+42

86 = 42 (2)+2

42= 2(21)+0

HCF = 2

(iv) 632,790,869

a= bq+r

790= 632(1)+158

632= 158(4)+0

HCF = 158

158,869

a= bq+r

869 = 158 (5)+79

158= 79(2)+0

HCF = 79

(v) 291,582,776

a=bq+r

582=291(2)+0

HCF = 291

291,776

a= bq+r

776= 291(2)+194

291=194(1)+97

194=97(2)+0

HCF = 97

Answer 2

Answer:

144 = 84x1 + 60

84 = 60x1 + 24

60 = 24x2 + 12

24 = 12x2 + 0
