Question

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

Answer 1

Answer:

(a) 5

Step-by-step explanation:

( a) We found the factors and prime factorization of 25 and 45. The biggest common factor number is the GCF number. So the greatest common factor 25 and 45 is 5.

Answer 2

Answer:

(a) common factor = 5 and H. C. F. = 225

(b) common factor = 4 and H. C. F. = 84

(c) common factor = 8 and H. C. F. = 112

(e) common factor = 12 and H. C. F. = 180

(f) common factor = 14 and H. C. F. = 392

(g) common factor = 14 and H. C. F. = 84
