Answer:
(i) 60
(ii) 40 and 120
Step-by-step explanation:
(ii) Greatest common factor (GCF) of 40 and 120 is 40. We will now calculate the prime factors of 40 and 120, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 40 and 120.
The GCF of 120 and 360 is 120.
