Find the H C F using prime factorisation method (a) 16 and 60 ( b) 25 and 65 (c) 48 and 120​

Answer 1

Answer:

a.16= 2×2×2×2=2^4

60=2×2×3×5=2^2×3^1×5^1

LCM = 2^4×3×5

= 16×15

= 240

B. 25=5×5=5^2

65=5×13=5^1×13^1

LCM = 5^2×13^1= 25×65=1625

C. 48=2^4×3^1

120=2^3×3^1×5^1

LCM = 2^4×3^1×5^1

=240
