Question

1. Find common factors of the following numbers. Then find their HCF
(a) 25, 45,
(b) 12 28
(0) 16. 56
(e) 36, 60
(f) 56, 98
(g) 14,84
(h) 15. 80​

Answer 1

Answer:

a) Common Factors : 1 & 5

HCF = 5

b) Common Factors : 1,2,4,

HCF = 4

0) Common Factors : 1,2,4,8

HCF = 8

e) Common Factors : 1,2,3,4,6,12

HCF = 12

f) Common Factors : 1,2,7,14

HCF = 14

g) Common Factors : 1,2,7,14

HCF = 14

h) Common Factors : 1 & 5

HCF = 5
